So what does:
a = (if False: 1)
That's a good question. This is one of those areas where a definition would need to be created. My inclination is to say None (much like a function with no return statement).
Assuming the return value of "None", I go back to an example I gave earlier:
factors = for x in range(2, n): if n % x == 0: x
This doesn't work as intended (filtering out the non-factors). How to make it work? The only way I can think of is to make (if 0: 1) return a special "non-value" which loops will then filter out. But then we all know what happens to non-values.
So how would you solve this problem?
