Back in the 1990s, Apple's Hypercard accepted ≠ for "not equal". Of
course, Macs made it easy to type such special characters. By memory you
held down the Option key and typed an equals sign. For ≥ you used Option
and less-than. That worked in *any* Mac application.
Ah, glory days.
But I digress. In Python we can write the above as:
if x != 0:
[f1(y) if y >= 0 else f2(y) for y in s]
which for those not trained in algebra is probably more readable.
