The trick for the name mangling does not work at module level. Anyway,
if you read the PEP 8 [1] you can correctly write your code following a
well known coding standard. A function like this:

def _f():
    pass

is meant to be private, you can also state it in the function's
docstring to be more clear, if you want, but it's not necessary

Yes, and _f() will also be. There's no such thing as enforcing
encapsulation in Python, even the "__method()" trick can be easily
bypassed if you have to.
