Calling a function of a module by using its name (a string)
...attr(foo, 'bar')
result = method_to_call()
You could shorten lines 2 and 3 to:
result = getattr(foo, 'bar')()

You can use getattr in this fashion on class instance bound methods, module-level methods, class methods... the list goes on.
