How to add two decimals using python
The following example is for the user to input two numbers and calculate the sum of two decimals:
Example (Python 3.0) (Recommended learning: Python video tutorial)
# -*- coding: UTF-8 -*- # Filename : test.py # author by : www.runoob.com # 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))
The output result of executing the above code is:
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
In this example, we use user input Sum two numbers. The built-in function input() is used to obtain user input. input() returns a string, so we need to use the float() method to convert the string into a number.
For two-number operations, we use the plus sign ( ) operator for summation. In addition, there are also the minus sign (-), the multiplication sign (*), the division sign (/), and the floor division (// ) or remainder (%).
