# Python Project Setup Guide
This guide outlines a repeatable framework for setting up Python projects using virtual environments and effective package management.
## Setting Up a Virtual Environment
1. **Create Project Directory**
```bash
mkdir my_project && cd my_project
```
2. **Create Virtual Environment**
```bash
python3 -m venv venv
```
3. **Activate Virtual Environment**
- macOS/Linux:
```bash
source venv/bin/activate
```
- Windows:
```cmd
.\venv\Scripts\activate
```
4. **Deactivate Virtual Environment**
```bash
deactivate
```
## Package Management with pip
1. **Install a Package**
```bash
pip install package_name
```
2. **Install Specific Version**
```bash
pip install package_name==version
```
3. **Upgrade a Package**
```bash
pip install --upgrade package_name
```
4. **Using a Requirements File**
- Install packages:
```bash
pip install -r requirements.txt
```
- Freeze current packages to `requirements.txt`:
```bash
pip freeze > requirements.txt
```
## Managing Dependencies
- Create a `requirements.txt` file in your project root.
- List dependencies and versions, e.g., `flask==1.1.2`.
- Use `pip freeze` to generate this file with current environment packages.
## Best Practices
- Always activate your virtual environment when working on the project.
- Regularly update your `requirements.txt` to reflect new dependencies.
- Include `venv` in your `.gitignore` file.
- Commit `requirements.txt` to version control.
This guide provides a streamlined approach to setting up and managing Python projects, ensuring consistency and ease of use across development environments.
