Can't get Python to import from a different folder

I can't seem to get Python to import a module in a subfolder. I get the error when I try to create an instance of the class from the imported module, but the import itself succeeds. Here is my directory structure:

Server
    -server.py
    -Models
        --user.py

Here's the contents of server.py:

from sys import path
from os import getcwd
path.append(getcwd() + "\\models") #Yes, i'm on windows
print path
import user

u=user.User() #error on this line

And user.py:

class User(Entity):
    using_options(tablename='users')

    username = Field(String(15))
    password = Field(String(64))
    email    = Field(String(50))
    status   = Field(Integer)
    created  = Field(DateTime)

The error is: AttributeError: 'module' object has no attribute 'User'
