What is difference between python 2 and python 3?

 

Python is the most versatile programming language, commonly used for the development of various web applications and data analysis projects, machine learning, and a lot more. However, numerous learners often remain confused about how Python 2 differs from Python 3. At TCCI Computer Coaching Institute, we assist you in getting comprehensive guidance on the two versions by helping you realize their differences, so you select the right one for your project.

Introduction to Python Versions

Python 2 was released in the year 2000, which brought several improvements over its predecessor. Python 3 was released in 2008, which brought major changes to improve functionality, readability, and compatibility with modern technologies. Let's see the key differences.

Key Differences Between Python 2 and Python 3

1. Syntax Differences
2. Print Statement:

In Python 2, print is a statement:

python

2. print "Hello, World!"

In Python 3, print is a function:

3. print("Hello, World!")
4. Integer Division

 

Python 2 performs floor division by default:

python

Copy code

• print 5 / 2  # Outputs 2

In Python 3, division returns a float by default:

python
