Can I create custom PCB track layouts that include arcs using Python in KiCad?
Yes, you can create custom PCB track layouts that include arcs using Python in KiCad. The script provided shows how to programmatically add a track with a 90-degree arc between two pads:

```python
import pcbnew
import math
from pcbnew import wxPoint, wxPointMM

def add_track_arc(start, mid, end, layer=pcbnew.F_Cu):
    board = pcbnew.GetBoard()
    track = pcbnew.PCB_ARC(board)
    track.SetStart(start)
    track.SetMid(mid)
    track.SetEnd(end)
    track.SetWidth(int(0.25 * 1e6))
    track.SetLayer(layer)
    board.Add(track)

# Script to define start, mid, and end points for the arc
# ... (rest of the script)
add_track_arc(start1, mid, end1)

pcbnew.Refresh()
```

This script is particularly useful for intricate PCB designs where tracks need to navigate around obstacles or meet specific design requirements.
