Using Python 2.6 on ubuntu 10.04.
inspect module :
I want to 'inspect' a module and get a list of all
functions, classes and global variables in that module.

## A module has been imported, and we call `getmembers'
members = inspect.getmembers(mod)

## While iterating thru `members', we test to see
## if an object is defined in the module.
for m in members:
  obj = m[1]
  res = inspect.getmodule(obj)
## It appears that getmodule returns None for
## all but functions and classes.

Example, for a module name `mvcInstall', when a class
name `Install' that is defined in the module
is passed as an argument to inspect.getmodule, the
values returned is something like
"<module 'mvcInstall' from
'/home/tim/prj/cgi/libraries/python/mvcInstall.py'>"
Likewise for functions defined in the module.

** But ** when global variables such as strings, booleans,
integers are passed as an argument to getmodule, the
value returned is `None'.

What else can I do here?
thanks
