Python-equivalent of short-form "if" in C++ [duplicate]
While a = 'foo' if True else 'bar' is the more modern way of doing the ternary if statement (python 2.5+), a 1-to-1 equivalent of your version might be:
a = (b == True and "123" or "456" )... which in python should be shortened to:
a = b is True and "123" or "456"... or if you simply want to test the truthfulness of b's value in general...
a = b and "123" or "456"? : can literally be swapped out for and or
