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/pythona = 60      # 60 = 0011 1100 b = 13      # 13 = 0000 1101 c = 0c = a & b;    # 12 = 0000 1100print "Line 1 - Value of c is ", cc = a | b;    # 61 = 0011 1101 print "Line 2 - Value of c is ", cc = a ^ b;    # 49 = 0011 0001print "Line 3 - Value of c is ", cc = ~a;      # -61 = 1100 0011print "Line 4 - Value of c is ", cc = a << 2;    # 240 = 1111 0000print "Line 5 - Value of c is ", cc = a >> 2;    # 15 = 0000 1111print "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 12Line 2 - Value of c is 61Line 3 - Value of c is 49Line 4 - Value of c is -61Line 5 - Value of c is 240Line 6 - Value of c is 15
