📝 Usage Instructions

Save the script Save the above content to a file, e.g., install_python.sh.
Make it executable
chmod +x install_python.sh
Run the script with sudo
sudo ./install_python.sh

⚠️ Notes & Best Practices

Virtual Environments: After installation, create isolated project environments with:
python3.10 -m venv myenv source myenv/bin/activate
Don't override python3 globally unless needed Avoid changing system default unless you're sure. Use python3.10 and pip3.10 explicitly.
For Python 3.11+ Replace python3.10 with python3.11 (if supported by deadsnakes).
