generally you should keep all imports at the top of the file. There are 
times when importing only to specific methods or class is useful, but in 
general keep them at top.

and in those cases where you import to inside a class, the module 
becomes a class attribute so you use self. or ClassName. to reach the 
module:

class ClassName(object):
     import random
     def foo(self):
         print self.random.random()
         print ClassName.random.random()
