#The operating environment of this tutorial: Windows 7 system, Python 3 version, Dell G3 computer.
The user inputs two numbers and calculates the sum of the two numbers
# -*- coding: UTF-8 -*- # 用户输入数字 num1 = input('输入第一个数字:') num2 = input('输入第二个数字:') # 求和 sum = float(num1) + float(num2) # 显示计算结果 print('数字 {0} 和 {1} 相加结果为: {2}'.format(num1, num2, sum))
Output:
输入第一个数字:1.5 输入第二个数字:2.5 数字 1.5 和 2.5 相加结果为: 4.0
