I've hit a brick wall on something that I'm guessing is pretty simple but it's driving me nuts. I noticed that with python lists, generally when you make a copy of a list (ie, List1 = List2) List1 just becomes a reference to List2 and any modifications done to List1 affects List2. Ok I can live with this but I want to make a completely seperate copy not attached to the original in anyway. So then I used this method. List1 = List2[:] . This seemed to work in most situations, here I can modifiy List1 with out it affecting List2. But now I've run into an odd problem, and I have no idea why it's doing what it's doing. Here's some code
#some globle varibles bob = [[[0, 0]]]
I haven't gone through all of your code, but I suspect that the problem is that objects in the list (in this case, other lists) don't get copied only get referenced when you do bob[:]. This is expected.
See copy.deepcopy(). It will make sure that everything gets copied and nothing just referenced (more or less).
