Python 支持 3 种逻辑运算符：and、or 以及 not。逻辑运算符的优先级从高到低依次为：not、and 以及 or。not (100 > 50) # 结果为False，本来100>50的结果是True,但前面加了not就相当于反义，所以最后结果为False not (100 < 50) # 结果为True, 本来100<50的结果是Fals
print(a,'and',b,'is:', c) # False and False a =0 b=0 c = aandb print(a,'and',b,'is:', c) 执行和输出: Python 中的或操作可以使用 or 关键字。以下是在两个布尔值之间进行 or 操作的例子: # Python logical or operator # True or True a =True b =True c = aorb print(a,'...
>>> def false_func(): ... print("Running false_func()") ... return False ... >>> # Use logical and >>> false_func() and true_func() Running false_func() False >>> # Use bitwise and >>> false_func() & true_func() Running false_func() Running true_func() False ...
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 ...
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...

In this example, you use the Python equality operator (==) to compare two numbers. As a result, you get True, which is one of Python’s Boolean values. Speaking of Boolean values, the Boolean or logical operators in Python are keywords rather than signs, as you’ll learn in the sectio...
