If you enter data in a loop you need to accumulate the entries in some fashion. Re: ValueError - Not Working 17 Years Ago by babutche Thank You for your help. I had tried to put another "try, except" statement in my program but I didn't do it right. I never really thought about the "int(grade_string)". Right now I do not have any plans for any Tinker or other GUI interface. But I have done it before. I thought it was very hard and confusing.

It's worked before. 14 Years Ago by JustAnotherJoe Wow. I wish I could erase my entire moronic thread. Long story short. The code at work was the same as home. Somehow the modified code with the signal handler was overwritten at work and I didn't notice until I returned to the office location. I ASSumed. Mea culpa.

You have to edit your function like this ...

I believe the problem was "book" only had 2 elements in it (not 3). The second element was a list making book a 2d array. Anyway, I'm sure there is a more … Re: ValueError with script 16 Years Ago by vegaseat You can only load data with pickle that has been saved/dumped with pickle, since it saves the entire object as a byte stream, in your case the object would be the book dictionary. Here is an example ...

Thanks a lot Re: ValueError: unpack tuple of wrong size 16 Years Ago by BearofNH Lisa says: Please put code samples in between [noparse][code=Python][/noparse] and [noparse][/code][/noparse] brackets so it displays properly. As near as I can tell, moveHomer() returns a pair (row,column) and you are trying to unpack that into a 4-tuple. That just won't work. Re: ValueError: unpack tuple of wrong size 16 Years Ago by b04e3ian thanks I managed to figure it out. :) Re: ValueError: unpack tuple of wrong size 16 Years Ago by vegaseat b04e3ian, please use 4 spaces per indentation and try not to exceed 72 characters per code line, it will make your code much more readable for all of us. Good luck with your game and welcome to DaniWeb.

Re: ValueError: Mixing iteration and read methods would lose data 8 Years Ago by ~s.o.s~ Also, `next` takes an optional `default` argument so you can easily call `v0 = next(infile, None)` and check the value of `v0` before proceeding...
