Building a Simple Calculator with Python: with source code

  "Building a Simple Calculator with Python: A Step-by-Step Guide"

Introduction:

In this article, we will walk you through the process of creating a simple calculator using Python. This calculator program allows you to perform basic mathematical operations such as addition, subtraction, multiplication, and division. By following the steps outlined below, you will be able to create your own calculator and perform calculations effortlessly.

Step 1: Importing the Required Modules

To begin, we need to import the necessary modules. In this case, we will import the "logo" module from the "art" library. The "logo" module will add a visually appealing logo to our calculator interface, enhancing its overall appearance.

Step 2: Defining the Mathematical Operations

Next, we define the mathematical operations that our calculator will support. We create functions for addition, subtraction, multiplication, division, and percentage calculations. These functions take two numbers as input and return the result of the respective operation.

Step 3: Creating a Dictionary of Operations

We create a dictionary called "operations" to map each mathematical operation symbol to its corresponding function. This allows us to easily select the appropriate function based on the user's input.

Step 4: Designing the Calculator Interface

To make our calculator user-friendly, we print the imported logo using the "print(logo)" statement. This adds a visual element to the interface, making it more engaging for the user. We then prompt the user to enter the first number.

Step 5: Performing Calculations

Inside a loop, we display the available mathematical operations to the user. The user can select an operation by entering the corresponding symbol. We then prompt the user to enter the second number. The selected operation and the two numbers are used to calculate the result using the corresponding function from the "operations" dictionary.

Step 6: Providing Continuity and Clearing the Screen

After displaying the result, we give the user the option to continue performing calculations using the previous result as the first number. If the user chooses to continue, the previous result is stored as the first number, and the loop continues. If the user prefers to clear the screen and start afresh, the calculator function is called again.

Conclusion:

By following the steps outlined in this article, you can create a basic calculator using Python. This calculator allows you to perform addition, subtraction, multiplication, and division operations effortlessly. You can further enhance the calculator by adding additional mathematical operations or incorporating more advanced features. The possibilities are endless, and this simple calculator serves as a foundation for more complex calculator applications.
