Project Overview
In this project, Juni instructor Maya will be showing us how to use Python to build our very own calculator.
Learning outcomes:
Practice using conditionals, type conversion, and while loops.
Language: Python
Juni Level: Python Level 2
Core concepts: While loops, Conditionals, Arithmetic Operations
Lines of Code: ~50
Difficulty:Easy/Moderate
Est. Time: ~15-45min, but this varies by student and how creative you get!
Project Instructions:
Build your own program in Python that functions as a calculator. Think of how a typical calculator works in real life as your starting point, and then brainstorm how to break this down into smaller steps you'll need to add into your code.
This is how Maya broke down a calculator into implementable steps:
The user will input a number.
Then an operation.
Then another number.
And then the program will return the answer.
The calculator will keep asking for input until the user tells it to stop.
Try to do the project on your own first, and get creative with it if you want!

Looking up your coding questions is one of the best ways to learn!
Another great way to learn is from an experienced coder or instructor. Juni CS instructors like Maya work closely with students ages 8-18, and are specially trained to adapt to each child's unique learning style, pace, and interests.
