How do I get help within Python for an installed module?

Question

如何在Python中获得有关已安装模块的函数或方法的帮助？

Answer 1

You can always try help(your_function) in the Python shell. This will print the documentation ( docstring in Python lingo) of the corresponding function/class/package/... you're interested in.

If you're using IPython , you can also use your_function? .

Answer 2

You can use bpython , which has inline help like this:

Answer 3

To find the list of function in the module you can use

dir()
EX:
 import os
 dir(os)

And to access the docs of the module you can do

 os.__doc__
