Document 对象参考手册Python3 Examples

The following example calculates the area of a triangle by taking the lengths of its three sides as input from the user:

Example (Python 3.0+)

# -*- coding: UTF-8 -*- # Filename : test.py # author by : www.example.com a = float(input('Enter the first side length of the triangle:')) b = float(input('Enter the second side length of the triangle:')) c = float(input('Enter the third side length of the triangle:')) # Calculate the semi-perimeter s = (a + b + c) / 2 # Calculate the area area = (s*(s-a)*(s-b)*(s-c)) ** 0.5 print('Triangle area is %0.2f' %area)

Executing the above code produces the following output:

$ python test.py 
输入三角形第一边长: 5
输入三角形第二边长: 6
输入三角形第三边长: 7
三角形面积为 14.70
