[Tutor] all methods in a module

[Johan Meskens CS3 jmcs3]

hello
   
>>> import random
>>> print random.setstate.__doc__
Restore internal state from object returned by getstate().


my question is
" how can i loop through all the methods in a module 
  and print out their '__doc__' content ?

>>> for d in dir( random ):
	print random.???d???.__doc__


thanks
