Reference link to online documentation is invalid. (Probably) Should be: http://docs.python.org/library/userdict.html


Happens on Debian 7 Wheezy x86_64:

Hey drunax, I would like to create a patch for this and upload, but I don't see the link you are talking about. Is it in the documentation or is it in the file UserDict.py?

This problem is a duplicate of Issue16484.

The URL is generated by pydoc's getdocloc() when you use pydoc explicitly or through the interactive interpreter's help command.  But the doc web server is not set up to handle links for modules with mixed-case names, like UserDict; http://docs.python.org/2/library/userdict works.  Sean, you can add yourself to Issue16484 if you'd like to help.
