. Pythonic equivalent of "get_clock(THIS) or get_clok(THAT)" is
for flag in (THIS, THAT):
   try:
       clock = get_clock(flag)
   except:
       pass
   else:
       break
else:
   raise ValueError('Cannot get clock, tried THIS and THAT')
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.

           Programmers don't die, they just GOSUB without RETURN.
