计算机在底层实际处理的数据其实只有0与1两种,也就是采取二进制形式,二进制的每一个位(bit)也称为比特。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...
Python 位操作(Bitwise Operation) 详解 HexUp 创造是最高级的乐趣 来自专栏 · Pure for Fun 62 人赞同了该文章 什么是位操作 计算机中的数字都是用二进制形式表示的,在python里面,给数字加上前缀 '0b' 表示是二进制数字,如下示例,左边是二进制,右边是 ...
位操作是计算运算最本质的运算。 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...
比特操作-左移右移(slide to the left, slide to the right) 1 Note that using the & operator can only result in a number that is less than or equal to the smaller of the two values 2 Note that the bitwise | operator can only create results that are greater than or equal to the la...
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...

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...
A bitwise operator performs operations on the operands bit by bit 按位运算符逐位对操作数执行运算 Consider a = 2 (in binary notation, 10) and b = 3 (in binary notation, 11) for the below usages. 对于以下用法,请考虑a = 2(以二进制符号10)和b = 3(以二进制符号11)。
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...
