Suggested March 2024 Difference Between Module And Function In Python

Python is a high-level programming language. It is known for its optimization. It removes unnecessary aspects in programming and makes code effective. It is simple and easy to learn. Python allows to break the code into simpler parts so that it is easy to understand the code. It also allows us to reuse the code again hence reducing the number of lines of code. These are done using modules and functions.

All the classes, variables and functions that are important are collected and placed in a module so that they can be used at anytime and anywhere in programs. Modules can be used in multiple programs.

Function isolates a particular task from the entire program. It can be called whenever we need that task to perform.

Modules in Python

A module is a python file that contains functions, variables etc., in it and has .py extension. It is simply a python file that can be imported into another python program. The name of the module is the name of the python file itself.

As the number of lines of code goes on increasing in a program, it becomes difficult for us to understand that program. So, instead of writing all program in a single file, we can separate the code based on their functions into separate files that are referred as modules. This make the program clean and more readable. We can simply import those modules whenever needed using import statement. The syntax for importing module is given below.

import module_name

Here, module_name represents the name that we have given to that module while saving it. Importing module doesn’t allow us to use the classes and functions in it directly. In order to access them, we use dot operator (.) as given below

module_name.function ()

Modules contains codes for specific task. This code can have functions, classes, variables etc., A module can be used in more than one program. Hence, it promotes code reusability and reduces the number of lines of code.

Advantages of Using Modules

Code reusability − One can use the same module number of times

Simplicity − Modules perform only a specific task hence making them simple

Scoping − Module has a separate namespace for its identifiers so it avoids collisions with other identifiers

Functions in Python

A function is a block of code that performs specific task. It executes only when it is called. Functions are classified into the following types −

Built-in Functions

Functions that are readily available within the python library are known as built-in functions. There are many built-in functions available. Print (), input (), list (), dict () etc., are some of the built-in functions in python.

User-defined Functions

Functions that are created and defined by the user are known as user defined functions. The def keyword is used to create a user defined function. One must call that function in order to use it. Function must be defined first before we call it. Otherwise it shows an error.

User-defined programs divide large program into smaller segments so that the code is easy to understand.

The syntax for defining a function is as shown below −

def function_name (parameters): statements…

Here, function_name is the name we give to a function, parameters are the variables and statements represents the code and actual body of the function. Statements maybe a single or multiple lines of code. All the statements inside the function are indented to indicate that these statement blocks are present in a function.

The declared function can be called by specifying the name of the function followed by parenthesis as shown below:

function_name (arguments)

Arguments are the values that are passed to the parameters during a function call.

Code can be reused a number of times.

It prevents us from writing the same code again and again

Code becomes easy to understand if it is divided into multiple functions

A function call can be made anywhere in a program

Lambda Function

A function with no name is known as a lambda function. It is also known as Anonymous function. Lambda functions are created using the Lambda keyword. Lambda function can even accept another function as a parameter.

The syntax of the lambda function is given below −

lambda arguments: expression

Arguments are the values that are passed to the parameters during a function call and the expression is the statement being executed. It can have many arguments but the body of the lambda function can have only one statement in it.

Recursion Functions

Recursion functions are functions that calls itself repeatedly until the requirement is met.

Module vs Function in Python

The main difference between a module and a function is that a module is a collection of functions that are imported in multiple programs and can do various tasks. A function is a small block of code and separates itself from the entire code and have a fixed functionality. This function can be used anywhere within the same program whereas modules can be used in multiple programs.


Modules and functions both have one main goal that is code reusability. Functions are used for small tasks whereas modules are used for larger tasks as it allows various classes and functions in it. A module is used by importing it in another program where as a function is used by calling it.

Difference Between Class And Object In Oops

Key Differences between Class and Object

A class is a template for creating objects in a program, whereas the object is an instance of a class.

A class is a logical entity, while an object is a physical entity.

A class does not allocate memory space; on the other hand, an object allocates memory space.

You can declare a class only once, but you can create more than one object using a class.

Classes can’t be manipulated, while objects can be manipulated.

Classes don’t have any values, whereas objects have their own values.

You can create a class using “class” keyword, while hand you can create an object using “new” keyword in Java.

Class vs Object

What is Class?

A class is an entity that determines how an object will behave and what the object will contain. In other words, it is a blueprint or a set of instruction to build a specific type of object. It provides initial values for member variables and member functions or methods.

What is Object?

An object is nothing but a self-contained component that consists of methods and properties to make a data useful. It helps you to determines the behavior of the class.

For example, when you send a message to an object, you are asking the object to invoke or execute one of its methods.

From a programming point of view, an object can be a data structure, a variable, or a function that has a memory location allocated. The object is designed as class hierarchies.

Class vs Object – Difference Between Them

Here is the important difference between class and object:

Class Object

A class is a template for creating objects in program. The object is an instance of a class.

A class is a logical entity Object is a physical entity

A class does not allocate memory space when it is created. Object allocates memory space whenever they are created.

You can declare class only once. You can create more than one object using a class.

Example: Car. Example: Jaguar, BMW, Tesla, etc.

Class generates objects Objects provide life to the class.

Classes can’t be manipulated as they are not available in memory. They can be manipulated.

It doesn’t have any values which are associated with the fields. Each and every object has its own values, which are associated with the fields.

You can create class using “class” keyword. You can create object using “new” keyword in Java

Understand the concept of Java Classes and Objects with an example.

Let’s take an example of developing a pet management system, specially meant for dogs. You will need various information about the dogs like different breeds of the dogs, the age, size, etc.

You need to model real-life beings, i.e., dogs into software entities.

Moreover, the million dollar question is, how you design such software? Here is the solution-

First, let’s do an exercise.

You can see the picture of three different breeds of dogs below.

Stop here right now! List down the differences between them.

Some of the differences you might have listed out maybe breed, age, size, color, etc. If you think for a minute, these differences are also some common characteristics shared by these dogs. These characteristics (breed, age, size, color) can form a data members for your object.

Next, list out the common behaviors of these dogs like sleep, sit, eat, etc. So these will be the actions of our software objects.

So far we have defined following things,

Class: Dogs

Data members or objects: size, age, color, breed, etc.

Methods: eat, sleep, sit and run.

Now, for different values of data members (breed size, age, and color) in Java class, you will get different dog objects.

You can design any program using this OOPs approach.

Classes and Objects in Java

In the below program, we have declared a class called Dog. We have defined an object of the class called “maltese” using a new keyword. In the last statement System.out.println(maltese.getInfo()); we are displaying dog information like Breed, Size, Age, Color, etc.

class Dog { String breed; String size; int age; String color; public String getInfo() { return ("Breed is: "+breed+" Size is:"+size+" Age is:"+age+" color is: "+color); } } public class Execute{ public static void main(String[] args) { Dog maltese = new Dog(); maltese.breed="Maltese"; maltese.size="Small"; maltese.age=2; maltese.color="white"; System.out.println(maltese.getInfo()); } }


Breed is: Maltese Size is: Small Age is:2 color is: white

Types of Class

Following are the important types of class:

Derived Classes and Inheritance

A derived class is a class which is created or derived from other remining class. It is used for increasing the functionality of base class. This type of class derives and inherits properties from existing class. It can also add or share/extends its own properties.


A superclass is a class from which you can derive many sub classes.


A subclass is a class that derives from superclass.

Mixed classes

A mixed class is one more functionality that helps you to inherit the properties of one class to another. It uses a subset of the functionality of class, whereas a derive class uses the complete set of superclass functionality.

Uses of Class

Here are the important uses of class:

Class is used to hold both data variables and member functions.

It enables you to create user define objects.

Class provides a way to organize information about data.

You can use class to inherit the property of other class.

It can be used for a large amount of data and complex applications.

Use of Object

Here are the important uses of an object

It helps you to know the type of message accepted and the type of returned responses.

You can use an object to access a piece of memory using an object reference variable.

It is used to manipulate data.

Objects represent a real-world problem for which you are finding a solution.

It enables data members and member functions to perform the desired task.

Difference Between Ddr2 And Ddr3

DDR stands for Double Data Rate. The DDR RAM is capable of transferring data on both edges, i.e. falling edge and rising edge of the clock pulse. Thus, it doubles the data transfer rate, hence it named so. The DDR RAM also comes in several versions (or generations), such as DDR, DDR2, DDR3, DDR4, etc. Each version/generation of the DDR RAM offers enhanced performance in terms of speed, storage capacity, energy efficiency, etc.

In this article, we will discuss the two generations, i.e., DDR2 and DDR3 of the DDR RAM, and the important differences between them.

What is DDR2?

DDR2, Double Data Rate 2, is a version of DDR RAM. DDR2 is basically an improved version of its predecessor, i.e. DDR. Therefore, DDR2 offers higher data transfer speeds (typically 400 to 800 Mbps) and enhanced performance. DDR2 version of DDR RAM was first introduced in the year of 2003. At that time, this was very commonly used in most desktops and laptops.

DDR2 RAM has a higher storage capacity and it consumes less power. Another improvement made in DDR2 in comparison to DDR RAM is its clock speed, which means DDR2 RAM operates at a relatively faster clock speed than DDR RAM.

These days, DDR2 RAM is not used or rarely used. However, this can be found in older computer systems only.

What is DDR3?

DDR3, Double Data Rate 3, is an enhanced version of the DDR2 RAM. DDR3 RAM offer more enhanced performance in terms of data transfer rates, power consumption, storage capacity, clock speeds, etc.

DDR3 RAM provides a higher data transfer rate than DDR2 RAM, typically 800 to 1600 Mbps, which is almost double of the DDR2 version. Also, it consumes less power than DDR2. Although, in terms performance, it is not better as the DDR2.

Being a new generation DDR RAM, DDR3 RAMs are most widely used in modern desktops and laptops.

Difference between DDR2 and DDR3

The following table highlights all the important differences between DDR2 and DDR3:





DDR2 stands for Double Data Rate Version 2.

DDR3 stands for Double Data Rate Version 3.


DDR2 is cheaper than DDR3.

DDR3 is costlier.

Data Transfer Rate

DDR2 provides 4 knowledge transfer per cycle.

DDR3 provides 8 knowledge transfer per cycle.

Supply Voltage

Supply voltage required is 1.8 volts.

Supply voltage required is 1.5 volts.

Memory Reset

No memory reset option is provided in DDR2.

Memory reset option is available in DDR3 RAM.

Clock Speed

Clock Speed ranges between 400 MHz to 800 MHz.

Clock Speed ranges between 800 MHz to 1600 MHz.

Power Efficiency

DDR2 consumes more power than DDR3. Hence, it is less power efficient.

DDR3 RAM is more power efficient, hence it consumes less power.

Heat Generation

DDR2 RAM generates more heat, hence it requires cooling to increase system stability.

DDR3 RAM generates less heat, reducing the requirement of cooling


DDR2 has narrower bandwidth due to its slower clock speed.

DDR3 RAM has wider bandwidth than DDR2 RAM.

Per Module Storage Capacity

DDR2 has lower per module storage capacity.

DDR3 RAM has per module storage capacity higher than DDR2 RAM.


DDR2 RAM offers better performance as compared to DDR3.

DDR3 RAM offers average performance.


DDR2 RAM can have latencies between 3 and 9 cycles.

DDR3 RAM has a latency of 9 or 10 cycles.

Launching Year

DDR2 RAM was launched in 2003.

DDR3 RAM was launched in 2007.


DDR2 RAM was used in older computer systems.

DDR3 RAM is used in modern computer systems.


Both DDR2 and DDR3 are the versions of DDR RAM used in personal computers and laptops. The most significant difference between DDR2 RAM and DDR3 RAM is in their data transfer speed. DDR2 RAM provides a slower data transfer speed, typically between 400 to 800 Mbps; while DDR3 RAM provides a faster data transfer speed which is about 800 to 1600 Mbps. However, DDR3 is more expensive than DDR2 RAM.

Difference Between Host And Hostess

One of the significant discussions that have been on the rise is whether the terms host and hostess can be used in place of each other. The word Jody generally has varied applications and makes distinguishing them challenging.

One example we can see here is event management, considered a professional work genre. Among the other delegates, the hosts play an essential role in the success of both big and small events. The host’s professionalism depends on the parties, and there are special training schools to establish oneself as the host or hostess.

However, when we take a deeper look at each of the applications, they may shed light on what each stands for, and the difference between the host and the hostess is not just limited to gender.

Who is a Host?

The word host is said to be an umbrella term that includes all activities that are attributed to the person hosting an event. Although the word host sub-categorization is male and female, a host is commonly attributed to a male person who indulges himself in hosting different activities. A good personality always acts as a plus point to a suitable host; the host is chosen based on skills like the entertaining nature, reliability of the content spoken, etc.

A host might be the guest at some parties, and vice versa. This interchangeability of the roles plays a vital role in maintaining a rapport and initiating friendly relations. The word host, when used as a verb, indicates the act of managing the party when the guests arrive. When used as a noun, the word host refers to a male host only who is expected to drive the events based on the agenda.

The term host has subjective interpretations as well, and it can take on different definitions based on the application like −

A host is someone who receives the guest and entertains them for commercial and other official purposes or socially.

A host might also be someone who facilitates a function or an event and provides facilitates for the same.

A person who engages guests in a TV show or a radio program is also known as a host.

Who is a Hostess?

The term “hostess” is attributed to feminine features only, and no male can identify himself as a hostess, irrespective of the specified group of activities assigned for an event. The term hostess is commonly referred to a female flight attendant host; this is an exclusive post for females most widely referred to as an air hostess.

Special examinations and strict training mode take place before the selection of the hostess. The term hostess is attributed in two ways, one where the female hosts events and two to serve as a flight attendant throughout the journey.

The term “hostess” has many definitions based on its usage, including −

A hostess is paid to entertain guests or one who does it socially.

A woman in charge of seating diners in a public room is also referred to as a hostess.

A hostess is also employed on a public conveyance in cases like a flight attendant who caters to the needs of the passengers.

Differences between Host and Hostess

The main difference between the host and hostess is that the former is a male and the latter is a female; both these terms emerged when there was a need for assistance in the field of event management. The following are some more differences between the host and the hostess other than the gender.





A host is an individual who is expected to act as the representative of a party in front of the guests, the organizer of the party may also be but is female, with similar code

A host usually wears tuxedos in a formal gathering, and their attire traditional clothes and western management and extracting manipulating, serving food, and catering to the needs of the reliability

Hosts are usually preferred for large gatherings may be due to gender for traditional gatherings and gender, but they share many roles now. This plays for both the host and the hostess, and everything a host does, a hostess does too. The host and hostess invite guests, welcome them, provide them with food and drinks and entertain them. There has been a rise in the sharing of jobs between male and female workers. Hence, the role of the host is no longer reserved for the women or the hostesses only.

Both the host and the hostess work in unity for the active incorporation of all types of traits; whether or not it is a party or a business meeting, the management needs to delegate the work of hosting the people effectively to a good host. Apart from this, the host and the hostess are present to cater to the needs and queries and should have apt knowledge regarding the invitees for extra reference.

Difference Between Jpeg And Svg

JPEG and SVG are types of image formats. JPEG is a raster image format that uses a lossy compression algorithm to compress an image, whereas SVG is a highly scalable, text-based image format that uses mathematical structures to represent an image. JPEG images are used in photography applications, while SVG is used when high-resolution images are required.

JPEG is a good choice for photographs and other images with lots of colors, while SVG is a better choice for simple images and graphics that need to be resized, such as logos and icons.

Read this article to find out more about JPEG and SVG image formats and how they are different from each other.

What is JPEG?

JPEG stands for Joint Photographic Experts Group. JPEG is a raster image format that takes the “.jpg” or “.jpeg” extension. It uses a type of lossy compression to reduce file size, which means that some image data is lost when the file is compressed. Despite this loss of data, JPEG images can still be high quality and are widely used because they can be easily shared and downloaded.

JPEG is a standard image format that was created in 1992. JPEG is the most common image format used by digital cameras and other image capturing devices. Also, JPEG is the most common image file format for transmitting and storing photos on the Internet.

Technically, the JPEG image format is a standard that determines how an image is converted into a stream of bytes and converted back into an image file. JPEG file format is mainly used for photographs of realistic scenes with smooth variations of tone and colors. JPEG is also used for web images where reducing the data amount is important for fast response. However, it is not suited for line drawings, textures, icons, etc.

What is SVG?

SVG stands for Scalable Vector Graphics. SVG is a vector image format that is used to display images on the web. Unlike JPEG, which is a raster image format (made up of pixels), SVG is made up of lines and shapes that can be scaled to any size without losing quality. It is a unique image file format because its image quality remains same while zooming. This makes SVG a good choice for images that need to be resized, such as logos and icons.

SVG images are made up of paths and shapes. They are editable and can be scaled to any size without loss of quality. SVG images take the extension “.svg”. They are used in devices that are required to produce high-resolution images.

SVG images can be easily searched, indexed, and compressed. We may create SVG files using any vector graphics editor like InkScape, Adobe Illustrator, CorelDraw, etc.

Difference between JPEG and SVG

The following table highlights the important differences between JPEG and SVG image formats −
