Nope.

If you're using IPython, you can do svd?? .

That wasn't a question :) In IPython, '<entity>?' is roughly
equivalent to 'help(<entity>) ', whereas '<entity>??' displays the
code, if possible:

IPython 0.8.2 -- An enhanced Interactive Python.
? -Introduction and overview of IPython's features.
%quickref -Quick reference.
help -Python's own help system.
object? -Details about 'object'. ?object also works, ?? prints
more.

In [1]: from functools import wraps

In [2]: wraps??
Type: function
Base Class: <type 'function'>
String Form: <function wraps at 0x00CF31B0>
Namespace: Interactive
File: c:\python25\lib \functools.py
Definition: wraps(wrapped, assigned=('__mo dule__', '__name__',
'__doc__'), updated=('__dic t__',))
Source:
def wraps(wrapped,
assigned = WRAPPER_ASSIGNM ENTS,
updated = WRAPPER_UPDATES ):
"""Decorato r factory to apply update_wrapper( ) to a wrapper
function

Returns a decorator that invokes update_wrapper( ) with the
decorated
function as the wrapper argument and the arguments to wraps()
as the
remaining arguments. Default arguments are as for
update_wrapper( ).
This is a convenience function to simplify applying partial()
to
update_wrapper( ).
"""
return partial(update_ wrapper, wrapped=wrapped ,
assigned=assign ed, updated=updated )

Which is very handy, like most of IPython.
