这篇文章主要介绍了Python算术运算符实例详解的相关资料,需要的朋友可以参考下
Python算术运算符
以下假设变量a为10,变量b为20:
运算符 | 描述 | 实例 |
---|---|---|
+ | 加 - 两个对象相加 | a + b 输出结果 30 |
- | 减 - 得到负数或是一个数减去另一个数 | a - b 输出结果 -10 |
* | 乘 - 两个数相乘或是返回一个被重复若干次的字符串 | a * b 输出结果 200 |
/ | 除 - x除以y | b / a 输出结果 2 |
% | 取模 - 返回除法的余数 | b % a 输出结果 0 |
** | 幂 - 返回x的y次幂 | a**b 输出结果 20 |
// | 取整除 - 返回商的整数部分 | 9//2 输出结果 4 , 9.0//2.0 输出结果 4.0 |
以下实例演示了Python所有算术运算符的操作:
#!/usr/bin/python a = 21 b = 10 c = 0 c = a + b print "Line 1 - Value of c is ", c c = a - b print "Line 2 - Value of c is ", c c = a * b print "Line 3 - Value of c is ", c c = a / b print "Line 4 - Value of c is ", c c = a % b print "Line 5 - Value of c is ", c a = 2 b = 3 c = a**b print "Line 6 - Value of c is ", c a = 10 b = 5 c = a//b print "Line 7 - Value of c is ", c
以上实例输出结果:
Line 1 - Value of c is 31 Line 2 - Value of c is 11 Line 3 - Value of c is 210 Line 4 - Value of c is 2 Line 5 - Value of c is 1 Line 6 - Value of c is 8 Line 7 - Value of c is 2
