I'll try and expand on Steven's examples a bit, but really
gives you quite a lot of the information anyway. If you want help on
the "for" keyword, for example, type:
(As Steven said, note the quote marks.) If you want help on anything
else in Python at all, be it a function, module or object, then stick
that object in the brackets. Thus:
tells you all about Python's integers, while
>>> l = [1, 2, 3]
tells you about lists.
The only gotcha is that if you try getting help on a string object,
it thinks that you're trying to look up a keyword. In other words:
>>> s = "for"
get the same message.
