Since you make the common mistake of using the same name for the module
as you do for the class, it's hard to demonstrate. But if you used Pep8
naming conventions, the classes would be capitalized.
Instead of using
from x import X
Now, you still have a symbol x in your namespace, but it's just the
module, which is perfectly public. So you could access a dozen classes
within x, but only the module itself would be visible to others.
As someone else pointed out, you could also delete the module reference
when you're done with it.
