Python 2.x and Python 3.x are two major versions of the Python programming language. The main difference is that Python 3.x introduced changes to improve the language and fix inconsistencies, but these changes are not backward-compatible with Python 2.x.

The main difference is that Python 3.x introduced changes to improve the language and fix inconsistencies, but these changes are not backward-compatible with Python 2.x. For example, in Python 3.x, the `print` statement became a function (e.g., `print("Hello")` instead of `print "Hello"`). Python 2.x is no longer supported as of 2020, so Python 3.x is the recommended version for new projects. Here is my number Call 073-1485-0321. read less

In py2 the range functions returns the iterator objects while in py2 returns a list. This change was made to improve memory efficiency,especially when...

Python 2 is the older version of Python 3, Can say it as an enhancement of older version with new features Python 3 is not backward compatible to Python 2New features are having better unicode support and improved syntax In Python 2, the division operator / performs floor division for integers, while in Python 3, it performs true division, returning a floating-point result.Let me explain this with an exampleIn Python 2 Division between integers always return another integer for ex 7/4 would return 1Python 3 : Where as Division between integers will return actual value which is 1.75 In Python 2 The range function returns returns list of numbersPython 3 returns an iterator Many older libraries for Python 2 are not forward-compatible Most of the new libraries for Python 3 cannot be used in python 2 Compared to Python 2 Python 3 is more beneficial—particularly for new coders whichsupports AI, machine learning, and data science. In Python 2, print is treated as a statement whereas, in Python 3, print is treated as a function. Python 2 encloses exceptions in notations whereas Python 3 encloses them in parentheses. read less
