Python编程1——Python计算圆的周长和面积

前言

这是我对于”The Practice of Computing Using Python”的读书笔记。总结了这本书很多有趣的编程题目。初次练手大家轻拍。

Python计算圆的周长和面积

这个程序比较简单，直接上程序了。

#this is the programe taught by the book

import math 

radiusString = raw_input("Please input the radius of the circle: \n")
radiusInterger = int(radiusString)
circumference = 2 * math.pi * radiusInterger

area = math.pi*(radiusInterger**2)

print "The circumference of the circle is : " ,circumference ,"\n", \
      "The area of the circle is:" ,area
