At the prompt, type any of:
help()
help(module)
help(function)
help(any_object)
help("keyword") # note the quotes around the keyword
then hit Enter to get help about that object or keyword.
Many Thanks to you Steven, for such a concise explanation of using the
help. May I request some examples to make it a bit more explicit.
I'll try and expand on Steven's examples a bit, but really
help()
gives you quite a lot of the information anyway. If you want help on
the "for" keyword, for example, type:
help("for")
(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:
help(123)
tells you all about Python's integers, while
l = [1, 2, 3]
help(l)
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"
help(s)
and
help("for")
get the same message.
