解析python中的二进制位运算符

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; # 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
