python怎么算面积_python怎么计算面积？

用Python计算面积的知识点：

1、 长方形面积和三角形面积，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#!/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)
