hash and __eq__

I am writing a mapping object, and I want to ask about the details of __hash__ and __eq__. IIUC if I understand correctly, the Python dict's keys' hash codes are looked up first in O( 1 ), then all the matching hash entries are compared on equality in O( n ). That is, the hash code just really na

Using variables across modules

I'm having some trouble understanding how Python handles variables across multiple modules. I've dug through the documentation, but I still find myself at a loss. When you import a module, are you creating an instance of the variables within? For instance, if I have one file, "variables.py", which
