我是靠谱客的博主幸福哈密瓜，最近开发中收集的这篇文章主要介绍解析Python中的二进制位运算符，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

下表列出了所有的Python语言的支持位运算符。假设变量a持有60和变量b持有13，则：

示例:

试试下面的例子就明白了所有的Python编程语言提供了位运算符：

#!/usr/bin/python

a = 60      # 60 = 0011 1100 
b = 13      # 13 = 0000 1101 
c = 0

c = a & b;    # 12 = 0000 1100
print "Line 1 - Value of c is ", c

c = a | b;    # 61 = 0011 1101 
print "Line 2 - Value of c is ", c

c = a ^ b;    # 49 = 0011 0001
print "Line 3 - Value of c is ", c

c = ~a;      # -61 = 1100 0011
print "Line 4 - Value of c is ", c

c = a << 2;    # 240 = 1111 0000
print "Line 5 - Value of c is ", c

c = a >> 2;    # 15 = 0000 1111
print "Line 6 - Value of c is ", c

当执行上面的程序它会产生以下结果：

Line 1 - Value of c is 12
Line 2 - Value of c is 61
Line 3 - Value of c is 49
Line 4 - Value of c is -61
Line 5 - Value of c is 240
Line 6 - Value of c is 15
