Simon and all, What would you recommend? I don't know what I should code, because I haven't coded anything that loads a file.

Hi Nathan, > Traceback (most recent call last): > File "D:\Python24\exchange.py", line 28, in -toplevel- > exch = pickle.load(store) > File "D:\Python24\lib\pickle.py", line 1390, in load > return Unpickler(file).load() > File "D:\Python24\lib\pickle.py", line 872, in load > dispatch[key](self) > File "D:\Python24\lib\pickle.py", line 1207, in load_appends > mark = self.marker() > File "D:\Python24\lib\pickle.py", line 888, in marker > while stack[k] is not mark: k = k-1 > IndexError: list index out of range As you can see from the traceback, the error is occuring entirely in the pickle module. Which probably means your pickle file is corrupted. Or that you're trying to load your old exch.txt file which wasn't in pickle format. Simply delete 'exch.txt' and try again. Although you'll notice your program still doesn't work, because it tries to load 'exch.txt' even if there isn't an exch.txt. You should consider rewriting your program so that it checks to see if an 'exch.txt' file exists. If it does, it unpickles it. If not, it uses your default 'rates' variables. Speaking of rates, you have two typos in your code which you also need to fix. > exch = pickle.load(store) Should be rates = pick.load(store) And similarly, > pickle.dump(exch, store) pickle.dump(rates, store) Otherwise you're not saving or loading anyhing!
