So, take the good intentation from one and the single exit from the other:
def myMethod(self, arg1, arg2):
if some_bad_condition:
exitCode = bad1
elif some_other_bad_condition:
exitCode = bad2
elif yet_another_bad_condition:
exitCode = bad3
else:
exitCode = do_some_useful_stuff()
# possible common cleanup code here
return exitCode
Or, raise an exception on bad condtions rather then passing an error code.
