Knowing which Python you want on your path and that you want it on your path at all is somewhat of an advanced usage. While beginners do want to just open up cmd and type "python" and have it work, there are better ways to accomplish that which don't involve system-wide path manipulation or installation changes. Several PC manufacturers have been known to use Python for various system utilities, which is how Python sometimes ends up in the path on your grandma's Dell*. Even for a beginner who just wants "python" to work, we need to be careful to not wreck their entire system by helping them get our fresh Python install to show up. A more reasonable way to help beginners would be to create a shortcut somewhere that starts up cmd with a modified path. They can do whatever they want to do within that context without modifying their entire system. If they learn that they later want their system-wide path manipulated, they can do that within the installer or will known how to do that themselves. * watch Dave Beazley's PyCon 2014 talk for a good story involving one of those manufacturer installed Pythons: https://www.youtube.com/watch?v=RZ4Sn-Y7AP8 _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
