I use a windows installation of python and Manim. Firstly you need to install a version of python. You can download a version here Download Python | Python.org You should download the 64 bit installer for windows. You should now add python to the “PATH” variable so that you can run python from the command line.
Here is a video explainer for python installation
You also need to install a python editor. I use the pycharm community edition which can be downloaded from here.
