Python算术运算符

以下实例演示了Python所有算术运算符的操作：

#!/usr/bin/python
# -*- coding: UTF-8 -*-
 
a = 21
b = 10
c = 0
 
c = a + b
print "1 - c 的值为：", c
 
c = a - b
print "2 - c 的值为：", c 
 
c = a * b
print "3 - c 的值为：", c 
 
c = a / b
print "4 - c 的值为：", c 
 
c = a % b
print "5 - c 的值为：", c
 
# 修改变量 a 、b 、c
a = 2
b = 3
c = a**b 
print "6 - c 的值为：", c
 
a = 10
b = 5
c = a//b 
print "7 - c 的值为：", c
