How to Build a Calculator in Python Using Functions | Think In Code
In this video, we build a simple calculator project in Python using functions — covering add, subtract, multiply, and divide. This is the perfect wrap-up project for the functions section before we move into Strings. Follow along as we write clean, structured Python code using while loops, boolean flags, nested conditionals, and user-defined functions.
What you'll learn:
How to define and call functions in Python
Using while loops with a boolean flag
Nested conditional statements
Taking user input and converting to float
Handling invalid input gracefully
Whether you're a beginner or just brushing up, this project is a great way to solidify your understanding of Python functions.
