Python Program to Make a Simple Calculator

This quality can be utilized to make useful programs. For starters, you can ensure that the program continues to run even if the user types plankton when asked for a number. We are interested in seeing your solutions to this simple command-line calculator project!

You can also experiment with converting the input to floats. At this point, the program shows the equation performed and the product. Step 3 — Adding conditional statements With our calculator.

This tutorial presents a learning exercise to help you make a simple command-line calculator program in Python 3. You may want to consider other possible options for handling various situations.

However, we want to limit the program to only perform one operation at a time. You should be able to type into the terminal window in response to each prompt. Next, you may want to create a text-based game like tic-tac-toe or rock-paper-scissors.

Define again function to ask user if they want to use the calculator again def again: We would like to use a number in this program for 2 reasons: Lisa Tagliaferri Introduction The Python programming language is a great tool to use when working with numbers and evaluating mathematical expressions.

Please feel free to post your calculator projects in the comments below. Because of how we have structured our program, the if statement will be where the addition is performed, there will be 3 else-if or elif statements for each of the other operators, and the else statement will be put in place to handle an error if the person did not input an operator symbol.

Conclusion This tutorial walked through one possible approach to building a calculator on the command line. At this point, we should add the again function to the end of the calculate function so that we can trigger the code that asks the user whether or not they would like to continue.

For this, you may want to use exception handling with the try There are many ways to handle errors and modify and improve each and every coding project. Output Please type in the math operation you would like to complete: Step 1 — Prompt users for input Calculators work best when a human provides equations for the computer to solve.

We could choose whatever symbols we want, though, like 1 for addition, or b for subtraction. At this point, you can add the rest of the operators to the program with the same format we have used for addition:After writing our two lines, we should save the program before we run it.

We can call this program and in a terminal window, we can run the program in our programming environment by using the command python You should be able to type into the terminal window in response to each prompt.

Python Program to Make a Simple Calculator In this example you will learn to create a simple calculator that can add, subtract, multiply or divide depending upon the input from the user. To understand this example, you should have the knowledge of following Python programming topics.
