5 years ago Thanks, I will keep that in mind. Right now it's mostly for "remindability", less clutter than comments. For speed, I plan to move to Julia when it gets too slow anyway.

Do you know that syntax trick? Probably a bit faster, too. If there are elements of a tuple that won't be used, they could be skipped (readability ("remindability") could be preserved with a comment):
for y, x, , , , in P[2]: # y, x, i, dy, dx, g map[y, x] = True
instead of the full form:
for y, x, i, dy, dx, g in P[2]: map[y, x] = True
It could be done for any of the positions: for y, , , dy, _, g in P[2]: ... etc.
