Python 简单计算要求形状面积的实例

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

#!/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"
