Help() Function

I had a question regarding the help() function. When I typed help(str), the shell returned a bunch of attributes like the following: | add(self, value, /) | Return self+value.

However, when I typed in help(str.add), I got the following error: AttributeError: type object 'str' has no attribute 'add'

that's because str really does NOT have add attribute, but it has __add__. So if you type in

help(str.__add__)

It will show you sth related to __add__. Hope it helps.
