What's the best approach to execute the following using __import__ so that I may dynamically specify the module?
from module import *

A:
It's the same as a normal from-import call, you just pass it a list containing '*' for the fromlist:
moduleName = "foo"
__import__(moduleName, globals(), locals(), ['*'])

That doesn't actually setup locals() though, which is the issue I'm having :)

According to the doc the standard `__import__` doesn't even use the `locals` argument. If you override `__builtin__.__import__` you can see exactly what happens when you run `from foo import *`, it seems to do exactly that

It doesnt actual import the attributes, which is the problem. It loads them into memory but it doesn't set them under the current modules locals().

A:
__import__() never adds anything to the local scope. You will have to go through the returned module, accessing its attributes as desired.

The only way I found:
module = __import__(module, globals(), locals(), ['*'])
for k in dir(module):
locals()[k] = getattr(module, k)

Why would you want to do this? I smell bad code. || On the other hand, feel free to accept your own answers.
