This article is to share with you about how to achieve a calculator in Python. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article.

Code implementation

# define the function def add (x, y): "" add "return x + ydef subtract (x, y):" subtract "return x-ydef multiply (x, y):" multiply "return x * ydef divide (x)" Y): "divide"return x / y # user enter print (" selection operation: ") print (" 1, add ") print (" 2, subtract ") print (" 3, multiply ") print (" 4, Divided by ") choice = input (" enter your choice (1, 2, 3, 4): ") num1 = int (input (" enter the first number: ") num2 = int (" enter the second number: ") if choice = = '1percent: print (num1) "+", num2, "=", add (num1, num2)) elif choice = = '2percent: print (num1, "-", num2, "=", subtract (num1, num2)) elif choice = =' 3percent: print (num1, "*", num2, "=", multiply (num1, num2)) elif choice = = '4percent: print (num1, "/", num2, "=", divide (num1, num2)) else: print ("illegal input")

Output result:

Select operation:

1. Add up

2. Subtraction

3. Multiply

4. Division

Enter your choice (1), 2, 3, 4): 3

Enter the first number: 5

Enter the second number: 2

5 * 2 = 10

This is how to implement a calculator in Python. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
