A calculator is a program that performs arithmetic calculations and mathematical operations. In Python, you can create a simple calculator using basic arithmetic operators like addition (+), subtraction (-), multiplication (*), and division (/). Here is an example of a simple calculator program in Python:

Here is a step-by-step guide to making a simple calculator in Python:

4. the calculate function to perform the calculation, and save the result in a variable. For example


  1. Print the result to the screen. You can use the print() function to do this. For example:


  1. Save the file and run the program by typing python calculator.py in the terminal.

That's it! You now have a working calculator program in Python. You can customize the program by adding more operators or by including error handling to handle invalid input from the user. You could also consider building a GUI for the calculator using a library like Tkinter or PyQt. The possibilities are endless!
