How Python imports an instance of a class

I'm trying to find out how exactly importing works in Python.Let's say I have a foo.py module that contains the following class:

class Foo:     def __init__(self, *args, **kwargs):         ... foo = Foo() 

Now, I want to import it in other modules.

Is it going to use the same instance every time that I import it or will make different instances whenever I import it and is it even a good way to instantiate a class or it'd be better to import the Foo class and create an instance in modules that imported it(As it's obvious, this class doesn't need any args and kwargs).
