Wow -- you'd rather write nine lines of code instead of three?
clock = get_clock(THIS) or get_clock(THAT)
if clock is None:
raise ValueError('Cannot get clock, tried THIS and THAT')
Yes - to force people to write the last two lines. Without forcing
most programmers will skip them.
Forced? I do not use Python to be forced to use one style of
programming over another.
And it's not like returning None will allow some clock calls to work but
not others -- as soon as they try to use it, it will raise an exception.
