Can I use Python to reset my PCB layout in KiCad by removing all tracks?
Yes, you can reset your PCB layout in KiCad by removing all tracks using Python scripting. The script provided offers a straightforward way to delete every track on the board, effectively resetting the layout:

```python
import pcbnew

board = pcbnew.GetBoard()
for t in board.GetTracks():
    board.Delete(t)

pcbnew.Refresh()
```

This method is especially useful for PCB layouts that require significant revisions or when starting the routing process anew is more efficient than modifying existing tracks.
