I prefer to test explicitly for the truth value of the list. I don't want to test whether the length of the list is greater than 0 (in fact, I don't care about the length property of the list at all) - I want to know whether the list is empty (or not empty). The Python syntax for this test is if lst: # not empty or if not list: #empty The view "let me test for the precise value" leads to formulations like if foo is True: return True else: return False People should have more trust in boolean conversions.
