Each of these functions will simply take two parameters, a and b and return the specified operation on a and b. def add (a, b): return a + b def subtract . We are going to create only a simple calculator that can perform addition, subtraction, multiplication and division. We are going to make a 3 by 3 Grid with buttons that represent the possible inputs, a live result showing system, a history of calculations feature, and variable insertion. First, you can ask for numbers using a loop, and in the loop, place the entered numbers into a list: nums = int (input ("How many numbers you want to calculate?\n")) entered_nums = [] for n in range (nums): x = float (input (f"Enter the {format_number (n + 1)} number: ")) entered_nums.append (x) When run, I get: shidhu / Simple-Calculator Star 6 Code Issues Pull requests It is a calculator software developed by python. num1 = int (txtArea1.text ()) num2 = int (txtArea2.text ()) Performing Arithmetic Operation Based on User Input: Perform the arithmetic operation on user input num1 and num2 is pretty easy. In this video we'll build out the main GUI for the Calculator App. Calculator Application is developed using Python programming language to calculate and perform calculation operations. operator=operator + str (numbers) is used as an operator. The history of operations, results, and unprocessed input is stored in `SimpleCalculator.log`. The rest is easy: miles = get_input ("Enter distance traveled (in miles):", "Distance traveled must be a number larger than 0") gas = get_input ("Enter gasoline consumed (in gallons):", "Gasoline consumed must be a number larger than 0") mpg = miles/gas. # import everything from the tkinter module from tkinter import * # initializing the main window (container) calculator = tk () # assigning our main window a title calculator.title ("simple calculator") # this is the screen that will serve as our display inputscreen = entry (calculator, borderwidth=5, width=35) # positioning the input Step 5: Assign actions to buttons.
