Looking for an intellisense with good help IDE for Python

[metaperl]

Hi,

I would like an IDE that shows me all methods and functions I can call
on a particular data item. For instance, iter() can be called on any
sequence, but it is not a method.

Nonetheless, I would like for something to show me every thing that I
can call on a particular data item.

This includes % after a string.

I would also like browseable help with good examples on whatever
methods and functions and operators it pops up.

Thanks,
Terrence
