You need to tell "assigner()" that foo doesn't belong to the local
(function) namespace, but rather comes from the global namespace:

In [1]: def foo():
   ...:     return None
   ...:

In [2]: def bar():
   ...:     print "called bar"
   ...:
   ...:

In [3]: def assigner():
   ...:     global foo
   ...:     foo = bar
   ...:
   ...:

In [4]: assigner()

In [5]: foo()
called bar
