I'm studying old code that uses urllib.splituser() call and can't find description of this function in Python 2.6.6 docs.

splituser is an internal API. It has never been exposed through Docs anytime and there are good reasons for that too. We never want internal helper functions (even tough they don't startwith _) be exposed through docs as it may clutter the API Documentation. 

If you find a good use for splituser like function, it would good to discuss and build upon current one before exposing. 

I am closing this as wontfix.

Hi Senthil,
what do you think about "documenting" those methods are private ones in the urllib code (if not using _, at least a short comment above them)? at least we have a mark it's an implementation decision and in case someone has the crazy idea :) to scan the module to fill in the missing methods in the doc, he'd know they are not to be exposed.

Sandro, I don't think is a required. Those functions serve the purpose
of making the module code modular. They are helper functions for the
module and are not really useful outside of it, when used standalone.
Think about , splituser, splitpath, splitport etc etc. 
I think, it is best that they remain as such, undocumented.
