#!/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:
1
2
3
4
5
6
|
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
