dir(), help() and the interactive interpreter (IDLE or CLI) are your
best friends.
Any time you wonder what an object does, or if you do something to an
object, fire the interpreter, create your object, abuse it via
dir/help/whatever, and then use dir/help/whatever on the results of
dir'ing your object.
Oh, and use new style classes too (explicitly inherit from `object` or a
built-in type), they are much more flexible and interesting than
old-style classes
>>> class Test: # old style class
pass
>>> test = Test()
>>> dir(test) # are completely uninteresting
['__doc__', '__module__']
>>> class Test(object): # new style classes on the other hand
pass
>>> test = Test()
>>> dir(test) # have 2500% more sexyness
['__class__', '__delattr__', '__dict__', '__doc__', '__getattribute__',
'__hash__', '__init__', '__module__', '__new__', '__reduce__',
'__reduce_ex__', '__repr__', '__setattr__', '__str__', '__weakref__']
