Hi,
I am using the builtin __import__() to import modules. That works for
simple modules like in this example:
m= __import__("egg s")
when there is the module "eggs.py" in the current directory
But how do I do this with packages? A I understand the documentation for
__import__(), it must be something like:
m= __import__("egg s", globals(), locals(), ["spam"])
when there is the package "spam" in the current directory, containing
the module "eggs".
But that doesn't work. I tried it in some different forms. The only one
that works in some way is:
m= __import__("spa m.eggs")
But that is not what I want, since I get "spam" as a module:
<module 'spam' from 'spam/__init__.pyc'>
So what am I doing wrong here?

Look again at the documentation for __import__. In particular, you
want a function like the following, given in the dicumentation:
def my_import(name) :
mod = __import__(name )
components = name.split('.')
for comp in components[1:]:
mod = getattr(mod, comp)
return mod
Then, you do
eggs = my_import("spam .eggs")
I have to admit, I find this annoyingly subtle - 99.99% of the time,
it's my_import() that you want, but you have to define it yourself...
Ah, well. I hope this helps.

You're doing everything correctly, just not quite enough.
What you've got is an almost empty module named "spam",
which contains another module bound to the identifier "eggs".
So what you need to do is:
m = __import__("spa m.eggs")
eggs = spam.eggs
This will probably also work:
eggs = __import__("spa m.eggs").eggs

There is an easier way: all imported modules are listed in the
sys.modules namespace dictionary. So,
import sys
__import__('spa m.eggs')
my_module = sys.modules['spam.eggs']

If this is a FAQ, please let me know where the answer is.
I have in some code an 'eval', which I hate, but it's the shortest
path to where I need to get at this point. I thought that one way I
could harden the enviroment against malicious code would be to
temporarily disable the import statement by overloading __import__,
but I tried what seemed obvious to me, and it didn't work.
What I want do do is something like this:

Hi, I'm writing a gdesklets control, that dynamicly uses __import__ and

I looked through the list but could not find any solutions for my

Within my program, I am importing a module via

not to save them
in a config module or a Config class but rather use the globals and
