# Python Projects
2+
3+
An open-source GitHub repository containing Python project ideas, steps, tips, and code solutions.
4+
5+
This repository is designed to help Python learners at all levels, starting with beginner-friendly projects and gradually progressing to more advanced ones. Each project includes clear instructions and a working code implementation.
6+
7+
## Table of Contents

2. [Beginner Projects](#beginner-projects)
10+
3. [Contributing](#contributing)

12+
13+
## Setup
14+
15+
- Make sure that you have at least Python `3.6` or later (we recommend `3.12`) installed on your computer. You can do a quick search and download it from a trusted provider for your platform.
16+
17+
- Make sure that you have an IDE, or a place where you could code and run the Python interpreter.
18+
> [!TIP]
19+
> We use Visual Studio Code. It's fast, efficient, and has many extensions and customizability options.
20+
21+
## Beginner Projects
22+
These projects are ideal for those new to Python. Each project includes a description, steps to follow, and tips for completing it.
