Answer 
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. 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.

Python 2.x is older version than 3.x and there are many major differences between these two. It lies in the way they handle iterators and the loopss. 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 dealing with large range and huge data.

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 which supports 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.
