Pydoc not working in Python 3.3 in Windows

Question

I am trying to generate the help text at runtime and i am not able to use the pydoc command in Windows. When i type

>>> pydoc(atexit)
Traceback (most recent call last):
  File "<console>", line 1, in <module>
NameError: name 'pydoc' is not defined

I have already set up the environment variables for pydoc.py file. C:\Python33\Lib\pydoc.py.

This also not works like it works for >>help('atexit')

>>> pydoc('atexit')
Traceback (most recent call last):
  File "<console>", line 1, in <module>
NameError: name 'pydoc' is not defined

Whats the possible reason for it.

Updates:

>>> import pydoc
>>> pydoc(sys)
Traceback (most recent call last):
  File "<console>", line 1, in <module>
TypeError: 'module' object is not callable
>>> pydoc('sys')
Traceback (most recent call last):
  File "<console>", line 1, in <module>
TypeError: 'module' object is not callable

Answer 1

Like any library in Python, you need to import it before you can use it.

Edit What exactly are you trying to achieve? Modules are indeed not callable. pydoc.help is the function you want, although I don't really know why you need it, since as you note the standalone help function does the same thing already.
