Seeing "locals()" from imported function

[=?ISO-8859-1?Q?Luis_M._Gonz=E1lez?=]

I apologize for this very basic question, but I can't understand how
this works...
I want to import a function from module B into my main script A, so
this function can see and use the locals from A.

For example:

def auto():
urls = ['/', 'index']
for k,v in __main__.locals ().items(): # these "locals"
are the ones of the main script
if isinstance(v,ty pe) and k != 'index':
urls.append('/%s' %k)
urls.append(k)
return tuple(urls)

Of course this doesn't work...

Any hint?

Luis
