Python's return has nothing to do with with gosub ... return in Basic. I 
believe the analog to Python's

return <some-value>

in VB is

<function-name> = <some-value>
exit function

I. e.

Function f(a, b)
    If a > b Then
        f = 42
        Exit Function
    End If
    f = a + b
End Function

translates to

def f(a, b):
    if a > b:
        return 42
    return a + b

in Python.
