iPython help, Docstring [source file open failed]

[Kegan]

I use iPython installed from macport. When I am in the iPython shell,
I do the following:


In [8]: from datetime import timedelta

In [9]: timedelta??
Type: type
Base Class: <type 'type'>
String Form: <type 'datetime.timedelta'>
Namespace: Interactive
File: /opt/local/Library/Frameworks/Python.framework/
Versions/2.5/lib/python2.5/lib-dynload/datetime.so
Docstring [source file open failed]:
Difference between two datetime values.


Lets say I want more information about timedelta right at the shell
(as oppose lookup at Python Doc). Can I somehow link the actual Python
source code to iPython so that it can be accessed in that way?

I am using macport. Please help.

Notice that the filetype is '.so'. That means it is a compiled
C module, so there is no python source to view.

You may want to try:
import pydoc
b = pydoc.render_doc(timedelta)
print b

Isn't this exactly the same output you get from typing 'help
(timedelta)' though?

Well, from this:

I understood that Kegan wanted python documentation, as in help, but
without the pager, right at the shell. Correct me if I'm wrong.
