Just one last question, how can I unistall python? It came with VS, as I said, and the only thing I can see is that I've got py.exe in C:\Windows and if I run py -m ensurepip I've got
Requirement already satisfied:setuptools in c:\program files (x86)\microsoft visual studio\shared\python36_64\lib\sitepackages
Requirement already satisfied:pip in c:\program files (x86)\microsoft visual studio\shared\python36_64\lib\sitepackages

Sorry, I am just a confused beginner.
