Import speeds

[musicfreak]

I tried Googling around for this but I couldn't find anything useful.

I know Python caches modules so they only have to be imported once, but is there a performance hit when using the wildcard import? For example, is this...

from some_module import *

...slower than this?

import some_module

Thanks in advance.

In cases of large modules (like PyQt4), then yes, the wild card import is slower, as it takes all the objects and fills them into your current name-space.
