让我们制作一个计算器

num1 = 2num2 = 3print(num1+num2) 5

num1 = 7num2 = 5print(num1-num2)2

num1 = 5num2 = 5print(num1*num2)25

num1 = 100num2 = 5print(num1/num2)20

quotient = 5//2remainder = 5 % 2print(quotient , "," ,remainder)2 , 1

num1 = 3num2 = 3print(num1**num2)27

# additionnum1 = int(input("enter number 1 : "))num2 = int(input("enter number 2 : "))result = num1+num2print("result is : ", result)enter number 1 : 1enter number 2 : 4result is :  5

# to make it possible in decimals too we use floatnum1 = float(input("enter number 1 : "))num2 = float(input("enter number 2 : "))result = num1+num2print("result is : ", result) enter number 1 : 1.5enter number 2 : 2.5result is :  4.0
