Inconsistency in python help('string') versus help(list)?

Question

When I type help(\'string\') in the python interpreter I get information about the string class. There,upper() is indicated as a function. Yet I can on

Answer 1

There's nothing wrong with what you see.

>>> help('string')

Will show you the string module documentation. And it looks like there's an upper function inside:

>>> import string
>>> string.upper('hello')
'hello'

I'd say that this upper is the same that is called if you do:

>>> 'hello'.upper()

But I'm not sure.

Notice that a string '' is a str type not a string type. This means that you're probably looking for:

>>> help('str')

And here you'll see too the str.upper method.
