Python语言支持以下位运算符
| 操作符 | 描述 | 示例 |
|---|---|---|
| & |
二进制和
|
(a & b) (二进制表示为 0000 1100) |
| | |
二进制或
|
(a | b) = 61 (二进制表示为 0011 1101) |
| ^ |
二进制异或运算
|
(a ^ b) = 49 (二进制表示为 0011 0001) |
| ~ |
二进制的补
|
(~a ) = -61 (二进制表示为1100 0011以2的补码形式，由一个带符号二进制数) |
| << |
二进制左移
|
a << = 240 (二进制表示为 1111 0000) |
| >> |
二进制右移
|
a >> = 15 (二进制表示为 0000 1111) |
示例
#!/usr/bin/python3
a = 60 # 60 = 0011 1100
b = 13 # 13 = 0000 1101
print ('a=',a,':',bin(a),'b=',b,':',bin(b))
c = 0
c = a & b; # 12 = 0000 1100
print ("result of AND is ", c,':',bin(c))
c = a | b; # 61 = 0011 1101
print ("result of OR is ", c,':',bin(c))
c = a ^ b; # 49 = 0011 0001
print ("result of EXOR is ", c,':',bin(c))
c = ~a; # -61 = 1100 0011
print ("result of COMPLEMENT is ", c,':',bin(c))
c = a << 2; # 240 = 1111 0000
print ("result of LEFT SHIFT is ", c,':',bin(c))
c = a >> 2; # 15 = 0000 1111
print ("result of RIGHT SHIFT is ", c,':',bin(c))
当你执行上面的程序它产生以下结果 -
a= 60 : 0b111100 b= 13 : 0b1101 result of AND is 12 : 0b1100 result of OR is 61 : 0b111101 result of EXOR is 49 : 0b110001 result of COMPLEMENT is -61 : -0b111101 result of LEFT SHIFT is 240 : 0b11110000 result of RIGHT SHIFT is 15 : 0b111
