a question that can accelerate learning python?

[wangziqing1984 at hotmail.com]

I am new to python .But interest in it .
I think if python could provide a method that show every method of an
object or an module.it will be great! We can save a lot of time to
find the document
take win32com as an example:
if code like this
"win32com.query"(or some other name that means query)
it would return a list of module or method that win32com have.
Does python have implement such interface yet? 'cause  I have not  so
familiar with python.
best wishes!
