Try  help my list    to get built-in help messages

In python  help my list append  for example  will give you the docstring of the function    gt  gt  gt  my list       gt  gt  gt  help my list append       Help on built-in function append       append              L append object  -- append object to end

Or  help list append    if you re generally poking around

User · Answer

You can use pydoc   Open your terminal and type python -m pydoc list append  The advantage of pydoc over help   is that you do not have to import a module to look at its help text  For instance python -m pydoc random randint   Also you can start an HTTP server to interactively browse documentation by typing python -m pydoc -b  python 3   For more information python -m pydoc
