Python is the most popular scripting language being used at the time of this writing, having surpassed perl and being more cross-platform-friendly than bash and other shell scripting languages.
Python is similar to C and perl languages and isn't too hard to pick up of you are familiar with programming. It's also often used for teaching programming. Really, its worth getting familiar with.
I strongly recommend installing python after the Git+MinGW tutorial
Python 2 or 3?
Haha, welcome to the biggest debate in the Universe. My suggestion is, you should stick with Python 2.7 - that's what everything is compatible with. Many programs/scripts and libraries are not Py3 compatible and the changes, while often back-compatible, just aren't ported to older things
So, if you write new code, its a good idea to make em work with Python 3 but I still use Py 2.7
Visit https://www.python.org/downloads/ to download the latest version. As of this writing its 2.7.11
I do suggest Add python.exe to Path so you can just run it from the command line
Once done, you can start up a new command line and run python
So say you want to install the python packages click and gitpython - just run pip install click gitpython
and it'll be done for you!
