Python語言支援以下位運算子

(a & b) (二進位制表示為 0000 1100)

(a | b) = 61 (二進位制表示為 0011 1101)

(a ^ b) = 49 (二進位制表示為 0011 0001)

(~a ) = -61 (二進位制表示為1100 0011以2的二補數形式，由一個帶符號二進位制數)
<<

a << = 240 (二進位制表示為 1111 0000)
>>

a >> = 15 (二進位制表示為 0000 1111)

### 範例

```#!/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))
```

```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```
