Python Projects for Kids

By: Jessica Ingrassellino

Overview of this book

Kids are always the most fast-paced and enthusiastic learners, and are naturally willing to build stuff that looks like magic at the end (when it works!). Programming can be one such magic. Being able to write a program that works helps them feel they've really achieved something. Kids today are very tech-savvy and cannot wait to enter the fast-paced digital world. Because Python is one of the most popular languages and has a syntax that is quite simple to understand, even kids are eager to use it as a stepping stone to learning programming languages. This book will cover projects that are simple and fun, and teach kids how to write Python code that works. The book will teach the basics of Python programming, installation, and so on and then will move on to projects. A total of three projects, with each and every step explained carefully, without any assumption of previous experience.

The calculator


The first calculator was invented in 1966 at Texas Instruments (http://www.ti.com/corp/docs/company/history/timeline/eps/1960/docs/67-handheld_calc_invented.htm) and was able to do addition, subtraction, multiplication, and division. The calculator had eighteen keys and could display twelve numbers on the screen. While it doesn't seem like much at first, especially compared to the technology we now enjoy, there is quite a lot of code and decision making that go into the operations that a basic calculator performs.

When we want to figure out how something works, we need to break it down into smaller parts. Let's take a look at how the calculator adds numbers together:

  1. First, the calculator needs power.

  2. The user enters the first number.

  3. The user presses an operation key (+, -, *, or /).

  4. The user enters a second number.

  5. The user presses the = key.

  6. Then, an answer is printed to the screen.

On a basic calculator, the computer does not keep all of the numbers on the screen. The computer...
