逻辑运算符包括 and“与”、or“或”、not“非”。假设a = 6,b = 66。and 与:x and y,如果x为假(False),那么返回假,否则返回 y 的值。如:a and b,返回b的值 66。or 或:x or y,如果x为真(True),那么返回 x 的值,否则返回 y 的值。如:a or b,返回a的值 6。not 非:not ...
逻辑运算符有些时候我们想要一次检查多个判断条件,为此可以使用逻辑运算符(logical operator)。Python 支持以下三种逻辑运算符:andornot逻辑与(and)运算符逻辑与(and)运算符用于检查两个条件是否同时为 True:a and b如果两个条件都为 True,返回 True;如果任何一个条件为 python 逻辑 与 python 逻辑运算符 and or...
and division have priority over addition and subtraction, while the special operators of remainder, modulus, and power have the same priority. There are three Logical connective in Python, and their operator priority order from low to high is or, and, and not. The final assignment operator ...

4.3 逻辑运算符(logicaloperators)逻辑运算符有三个:and,or和not。x > 0 and x < 0只有在x大于0且小于10时才为true。n%2 == 0 or n%3 == 0,若两个条件中的任一为true,则整个表达式为true,即数字n需要被2或3除尽。not运算符用于否定一个布尔表达式,not (x > y)在x > y为false时才为...
