This is the end of the stack trace: > File "C:\Python Project\Roguelike.py", line 966, in save_game > file['map'] = map > TypeError: 'type' object does not support item assignment Now, the map is randomly generated -- could that be an issue? Should I just scrap the current system and use pickle? > Please always give the complete stack trace, it's provided for a purpose. Here I'll grope around in the dark and guess that you need file_object = shelve.open(... -- Cheers. Mark Lawrence.
