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yb / 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
