#!/usr/bin/python
 
a = 21
b = 10
c = 0
 
c = a + b
print "Line 1 - Value of c is ", c
 
c += a
print "Line 2 - Value of c is ", c
 
c *= a
print "Line 3 - Value of c is ", c
 
c /= a
print "Line 4 - Value of c is ", c
 
c = 2
c %= a
print "Line 5 - Value of c is ", c
 
c **= a
print "Line 6 - Value of c is ", c
 
c //= a
print "Line 7 - 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 31
Line 2 - Value of c is 52
Line 3 - Value of c is 1092
Line 4 - Value of c is 52
Line 5 - Value of c is 2
Line 6 - Value of c is 2097152
Line 7 - Value of c is 99864
