So I'm just learning python still, and I've got this assignment to make a maze program (no graphics or any of that, just a text based one) and I'm trying to get it working, but the function I've written to find the legal moves keeps throwing errors.
The most recent one its thrown is TypeError: 'NoneType' object is unsubscriptable
I'll post the code below (not the whole thing, just the bits relevant to this bit cause the whole thing is over 200 lines). If someone out there could tell me how to fix it it would be GREATLY appreciated. Thank you :D

legals.append('S')
elif maze[row,col+1] == 'O' or 'F':
legals.append('E')
elif maze[row,col-1] == 'O' or 'F':
legals.append('W')
