How to learn a package in python

Question

import pkg
dir(pkg)

such an operator in python will not show all classes / functions / subpackages in the pkg package, because some of them can be loaded just in time. So what is the best way to learn the package in python?

Answer 1

Try pydoc

pydoc package

It’s the same as calling a help function, but you can do it from the command line, and of course you can go to the module, class or level of the function using dot notation.

Answer 2

Read the source, read the module documents.

Answer 3

You can use help(pkg)either explicitly the document, if available.
