Why Migrate to Python 3?

Python 3 introduces numerous enhancements, optimizations, and new features compared to Python 2. With Python 2 reaching its end-of-life in January 2020, upgrading to Python 3 is essential for accessing the latest tools, libraries, and security updates.

Python 3 provides better Unicode support, improved standard library functionality, and cleaner, more consistent syntax. Migrating ensures long-term maintainability and compatibility for your projects.

Common Changes Between Python 2 and 3

      
# Python 2: Print is a statement
print "Hello, World!"

# Python 3: Print is a function
print("Hello, World!")
      
    

      
# Python 2: Integer division
result = 5 / 2  # Outputs 2

# Python 3: True division
result = 5 / 2  # Outputs 2.5
