有个Q友问怎么写个程序能按照要求输入，再输出对应形状的面积？

我大概写了几行，没有考虑输出异常，重点想记录下 int 的接收，如下图

知识点就两个

1， 长方形面积 & 三角形面积，因为要从终端接收用户的多个参数输入，所以用了map(int, raw_input().split()) 这种方式

2. 圆面积只想保留小数点后两位，就用到了 %.2f 来接收

```python

!/usr/bin/python

--coding:utf-8 --

name = raw_input("Please input your name here : ") if name == '': print "we don't like anonymous" else: choose = input("Which shape would you like to choose 1:Rectangle, 2:Square, 3:Triangle or 4 Round? :") if choose == 1: width, height = map(int, raw_input("Input width and height here, like 5 8 :").split()) print "Area = %d" % (width * height) elif choose == 2: length = input("Input width and height here, like 4:") print "Area = %d" % length 2 elif choose == 3: width, height = map(int, raw_input("Input width and height here, like 5 8 :").split()) print "Area = %d" % (width * height / 2) elif choose == 4: diameter = input("Input diameter here like 3 :") print "Area = %.2f" % (3.14 * (diameter / 2) 2) else: print "Invalid choose" ```

以上这篇Python 简单计算要求形状面积的实例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持python博客。
