Here’s a quick listing of modules that are currently undocumented, but that should be documented. Feel free to contribute documentation for them! (Send via email to email@example.com.)
The idea and original contents for this chapter were taken from a posting by Fredrik Lundh; the specific contents of this chapter have been substantially revised.
Some of these are very old and/or not very robust; marked with “hmm.”
These modules are used to implement the os.path module, and are not documented beyond this mention. There’s little need to document these.
