Question about import

P: n/a
I'm a complete newbie to using Python. I have a small question about
importing modules.

Is there any difference between the two following statements, and what
(if any) are they?
from Module import *

and
import Module

Thanks.

Yes. As I said to someone else hereabouts not all /that/ long ago
(!), import Module is the computing equivalent to getting your toolkit out of the
cupboard and putting it on your workbench.
from Module import * is the computing equivalent of getting your toolkit out of the
cupboard, tipping the contents onto the workbench, and putting the box
back into the cupboard.

If "Module" contains "foo()", import Module means that you can call Module.foo()
from Module import * means that you can use foo(). But if your code or any other module
contains something called "foo()" then you get a name clash. That can
be nasty, because you can get everything working fine, and somebody
using a library that's supposed to be compatable with the one you've
tested finds it doesn't work.

For all but the very simplest of code, use import Module
