You can also patch the library to always return lists instead of generators.

def seriously_I_just_want_lists(func):
  def replacement(*args, **kwargs):
    return list(func(*args, **kwargs))
  return replacement

import otherlib
otherlib.somefunc = seriously_I_just_want_lists(otherlib.somefunc)

But I'd avoid it where you can.  While the idea of a list is simpler
than the idea of an iterable (and easier to get your head around)
iterables promise less and that makes them more flexible and easier to
composite.
