Python is one of the most popular programming languages today. It is used for Python Web Development, data science, AI, and more. But did you know there are different versions of Python? In 2025, you may wonder which version you should use: Python or Python 3. Let’s find out!

What is Python?

Python is a programming language created in 1991. It is easy to read and write. Many companies use Python because it helps build apps and websites quickly. Today, Python development services are in high demand.

What is Python 3?

Python 3 is the newer version of Python. It was released in 2008 to fix issues in older Python versions. Since then, all new updates have been for Python 3. If you hire dedicated Python developers, they will likely use Python 3.

Key Differences Between Python and Python 3

Here are some important differences:

1. Print Statement

  • In old Python, you write: print "Hello"

  • In Python 3, you write: print("Hello")

  • The newer version uses parentheses.

2. Division

  • In old Python: 5 / 2 gives 2 (rounds down).

  • In Python 3: 5 / 2 gives 2.5 (exact result).

3. Unicode Support

  • Python 3 supports more languages and symbols.

  • This helps in global applications.

4. Better Performance

  • Python 3 is faster and more efficient.

  • It uses less memory.

5. More Python Frameworks Support
