"return" is the same thing as "return None"

a plain "return" at the end of a function is entirely optional:
>>> def func1():
... print
...
>>> def func2():
... print
... return
...
>>> def func3():
... print
... return None
...
>>> import dis
>>> dis.dis(func1)
2 0 PRINT_NEWLINE
1 LOAD_CONST 0 (None)
4 RETURN_VALUE
>>> dis.dis(func2)
2 0 PRINT_NEWLINE
3 1 LOAD_CONST 0 (None)
4 RETURN_VALUE
>>> dis.dis(func3)
2 0 PRINT_NEWLINE
3 1 LOAD_CONST 0 (None)
4 RETURN_VALUE
</F>
