[Tutor] 2D array question [was (no subject)]
Mr. Kuhlman it says python is not configured for tk. Gaarrgh! Why do linux distros do this? Stooopid... You will need to fetch another version of Python with Tk support built in. Its a compile time option so you can either fetch the source an build it yourself or find a Suse package with Tk support already selected. Its really stupid for Suse to do that, it only saves a tiny amount of space and means you can't run any programs based on Tkinter... but on another note does anyone know how to make a 2d array? This should probably be a separate post. Also can you change the subject line in your posts so people can fiind the thread easily. I've changed it on this one to pick up the 2D array issue A 2D array is just a table. There are several ways to do that in Python but the easiest is just a list of lists: Think of a chess game as an example where the boars is represented by an 8x8 2D array: chessBoard = [ [0,0,0,0,0,0,0,0], [0,0,0,0,0,0,0,0], [0,0,0,0,0,0,0,0], [0,0,0,0,0,0,0,0], [0,0,0,0,0,0,0,0], [0,0,0,0,0,0,0,0], [0,0,0,0,0,0,0,0], [0,0,0,0,0,0,0,0] ] Now you can access the third row, 4th column with: chessBoard[2][3] # remember zero indexing! Is that clear? You can also use tuples similarly, or nested dictionaries. A lot will depend on the data you are storing and how you want to access it. Finally you can create a Class with bespoke methods to more closely model your problem, but the class will usaually have one of the above solutions internally anyhow! HTH.
