If you use the "import from X from Y" form you need to understand the 
implications. It isn't just a shorter way of referring to Y. You're also 
removing a level of indirection that you have when you refer to it via 
X.Y. This means that if someone rebinds X.Y you won't see that. 
Typically you don't care but in some cases you might.
