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
