I’ve had the complete opposite experience. I’ve yet to use a non-trivial Python library/framework where I didn’t end up having to dig through the source code to figure out how to do something. The dynamic nature of the language makes it hard to auto generate useful docs. With something like Doxygen you can easily know exactly what types a function expects, how to construct those types, etc.

...OTOH, digging through Python source code is more pleasant than C++. So it balances out I guess.
