Very short remarks about setting up Python in Windows
********************************************
I tested it with Windows 10.
Generally you must be able to open a command line. See e.g.
here:
https://www.howtogeek.com/235101/10-ways-to-open-the-command-prompt-in-windows-10/
I start all the lines that you should type in the command line with the  > sign. 
THere are many excellent resources on the web. So you can try to find more info by just
googling python + windows or something similar.

1.Python installation:
********************************************
I would recommend to install Python 2.7.
I followed the instructions from this website only till the Python installation section and setting up environmental variables section:
https://www.londonappdeveloper.com/setting-up-your-windows-10-system-for-python-development-pydev-eclipse-python/

Setting the environmental variables is crucial, please follow the instruction above and add both:
C:\Python27 
and 
C:\Python27\Scripts
pahts to the correct location.

If everything is setup correctly, you should be able to open a command line
and type:
> python

Upgrading pip and installing packages
********************************************
From the command line you should be able to do
> python -m  pip install --upgrade pip
> pip install numpy
> pip install ipython
> pip install matplotlib 

The syntax 
> pip install NAME_OF_THE_PACKAGE_TO INSTALL
Is the general way to install missing packages.

Editors
********************************************
You can choose whaterever editor you want. 
I tried Notepad++(https://notepad-plus-plus.org/) and Atom (https://atom.io/)

Once you install Atom you should install additional plugins for code running and autocompletion.
Open a command line and write:

> apm install script
> apm install autocomplete-python-jedi

The scrip plugin (see https://notepad-plus-plus.org/) allows to run your python script from Atom. So e.g. you have your file opened and
when you use ctrl+shift+b it should execute the  current file (main function).
