You should probably be looking in the documentation, not trying to feed it
into the interpreter.  (If you want to get help on a specific entity in
Python it's usually better to use the "help()" function, e.g:

>>> import os.path
>>> help (os.path.splitext)
Help on function splitext in module ntpath:

splitext(p)
    Split the extension from a pathname.

    Extension is everything from the last dot to the end, ignoring
    leading dots.  Returns "(root, ext)"; ext may be empty.

>>>

Note, trying to do "help(os.path.splitext)" would not have worked before I
imported the "os.path" module.  (Differently put: Whatever you want to get
help() on, must be known to the interpreter, so must either be built in or
previously imported.)
