logical operator: not and ORThe same as in C + +!, , | |, in addition to the wording of the different, the actual principle is the same.The operation also follows the short circuit principle. Since Python does not natively support the ++/--operator, it avoids the inadvertent and | | After the expression is added to the ++/--operator, and the actual program run has exceeded the expected effect, full screen search and error is slow to resolve.Condition
