What use cases would this be useful for? Presumably most developers are using tox or virtualenvwrapper to control their python version

Came here to ask the same question. Under archlinux python 3 is the default, which breaks scripts who don't specify that their are python 2 only and start with #!/usr/bin/python and not #!/usr/bin/python2. But even there as user I don't see the need for this tool.

Commented above as a reply to @calpaterson; I'll paste the same comment below.

At least Ubuntu can also switch the version of what "python" links to via setting a configuration.

How does this interact with pip?

At this point, p makes no attempt to manage pip versions. I have added this feature to the TODO and it will be implemented sometime in the future.

Thanks for the suggestion! :)
