Simple input-output interaction.

The user enters two numbers and calculates and outputs the sum of two digits: (try to do this with just one line of code)

Enter a radius to calculate the area of the circle.

#简单输入输出num =input ("Please input a number:") print (num) #计算两数字之和num1 =input ("First:") Num2=input ("Second:") Sum=float ( NUM1) +float (num2) print ("resultone:%.2f"%sum) #利用一行代码实现print ("resulttwo:%.2f"% (float (input ("one:")) +float (Input ( ("A:"))) #输入半径, calculates the area of the Circle Pai=3.14r=input ("Please input R:") Area=float (R) **2*float (PAI) print ("resultthree:%.2f"%area )
