The project allows you to view your current MAC address, set a custom MAC, and generate random valid MACs for privacy testing or experimentation.</p> <p>What I Learned</p> <p>Using subprocess: Running Linux commands safely from Python.</p> <p>Regex parsing: Extracting MAC addresses reliably across different systems.</p> <p>Random MAC generation: Ensuring valid formatting and avoiding conflicts.</p> <p>This project helped me understand real-world challenges like permission handling, edge-case parsing, and safe system command execution.</p> <p>Check out the code and experiment yourself: <br> <a href="https://github.com/Trifalic/Mac_Changer" rel="noopener noreferrer">https://github.com/Trifalic/Mac_Changer</a><br> Would love feedback, suggestions for improvement, or any tips on optimizing system-level Python scripts!</p> programming python ethical linux
