I am just wondering what the difference is between Python2, Python3, PyPy2, PyPy3 is. I already understand that Python3 is the latest version of python, however I have no clue as to what PyPy2 and PyPy3 are, apart from the fact that some syntax is different. Thanks.

Python is the language - Python 2 and Python 3 are different major versions.
PyPy is an implementation of that language - it happens to be implemented in Python itself. This is in contrast to something like CPython (the de-facto "standard" implementation), which is written in C instead. PyPy 2 and PyPy 3 are implmentations of Python 2 and 3, respectively.
