返回结果的每一位是 x 和 y 中对应位做 and 运算的结果,只有 1 and 1 = 1,其他情况位0x|y# 或操作,返回结果的每一位是 x 和 y 中对应位做 or 运算的结果,只有 0 or 0 = 0,其他情况位1~x# 反转操作,对 x 求的每一位求补,只需记住结果是 -x - 1x^y# 或非运算,如果 y 对应...
因此,我们可以使用位运算符(bitwise operator)来进行位与位之间的逻辑运算。 位逻辑运算符特别针对整数中的位值进行计算。在Python语言中提供了4种位逻辑运算符,分别是&、|、^与~ &(AND,位逻辑“与”运算符) 执行AND运算时,对应的两个二进制位都为1,运算结果才为1,否则为0。 例如,a=12,b=38,则a&b得到...

(Python Operator Types) Python operators can be classified into several categories. Python运算符可分为几类。 Arithmetic Operators Logical Operators Comparison Operators Bitwise Operators Assignment Operators (Python Arithmetic Operators) #create two variables ...
The bitwise OR operator (|) performs logical disjunction. For each corresponding pair of bits, it returns a one if at least one of them is switched on: The resulting bit pattern is a union of the operator’s arguments. It has five bits turned on where either of the operands has a one...
这里介绍的位运算,只是针对于bitwise,就是逻辑操作。包括按位与,按位或,按位取反,按位异或。 在说明一下,按位操作,得到的结果还是一个计算内存的二进制数。注意,就是一个二进制数,不管它代表的是什么,数值还是字符串还是图像还是视频等等。这里和逻辑运算符是有本质的区别的。
The second example shows how the bitwise OR operator works. In this case, the resulting bits are the logical OR test of the corresponding bits in the operands. In all the examples, you’ve used the built-in bin() function to display the result as a binary object. If you don’t wrap...
Bitwise operators are used to compare (binary) numbers:OperatorNameDescriptionExampleTry it & AND Sets each bit to 1 if both bits are 1 x & y Try it » | OR Sets each bit to 1 if one of two bits is 1 x | y Try it » ^ XOR Sets each bit to 1 if only one of two bits...
