login.login(), based on the precise code that you showed, appears
to be the correct thing.  I'm not actually trying to understand
how your code works, mind you, just looking at it syntactically.

If that's giving you the error you say it is, something else is
amiss.  Do you "shadow" the "login" that comes from the import
statement with a function somewhere, or a method, in the class
MyApp, which you didn't show?  You should be able to use the
interactive prompt to "import login" and "login.login" without
getting any kind of "no attribute" error.  If you can do that,
clearly the problem is in the MyApp module.  Otherwise you've
got something wrong with login.py after all.
