https://docs.python.org/3.3/using/windows.html Just wanted to let you know, these links: Installing on Windows <http://diveintopython.net/installing_python/windows.html>in “Dive into Python: Python from novice to pro <http://diveintopython.net/index.html>” by Mark Pilgrim, 2004, ISBN 1-59059-356-1For Windows users <http://swaroopch.com/text/Byte_of_Python:Installing_Python#For_Windows_users> in “Installing Python” in “A Byte of Python <http://www.byteofpython.info/>” by Swaroop C H, 2003 are dead. Also: I'd like to have both python 2.7 and 3.7.x installed on windows, but of course only one can be associated with .py files at one time. It there a way to switch without re-installing?
