What's unclear about returning None if no clocks match?
Nothing, but having to check error values on return functions are not
what you typically do in Python. Usually, Python functions that fail
raise an error.
Absolutely. "Errors should never pass silently."
Again, what's the /intent/? No matching clocks does not have to be an
error.
Please don't force Python users to write pseudo-C code in Python.
+1. 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')
