🐍 Py8R

This repository was created for educational purposes. It contains 100 examples of small scripts written in Python.

💡 The Idea

A few months ago I was started playing with Python. To learn some advantages and disadvantages of these language I started reading book from Real Python series (Python 3.5). The content from the book gaves me a very good basic understanding of the language. I decided to share these samples of code for other people who wants to start with Python.

📁 Repository Structure

Some of examples have more than only one solutions. You will find them in the directory with the task.
