yeah, you got it pretty much right.

One side comment.

def foo():
    result =3D computation()
    return result

is a little silly just write 'return computation()'.  In several language=
s=20
(not sure about python) writing the code this way allows the compiler to=20
optimize the function call so that the return result is written directly =
into=20
the caller's stack so no actual return is executed which means faster, mo=
re=20
efficient function calls.
