I'm still pretty green working with python but I figured making my own game from scratch with what I know would be good practice. I've got this connect four game together and it works in so far as switching between players and 'dropping' their respective pieces. Now I need a win condition, though honestly, I don't know where to start. I'd prefer some guidance as opposed to straight code for the sake of learning, but of course, any help would be greatly appreciated. Thanks. Quick note, the current while loop is simply for debugging. I was thinking about setting a variable 'winner' to False and doing the loop 'while winner False:' and have the win condition set this variable to True.

You have a 7x6 board, and you need to see if a line of 4 adjacent or diagonal spaces contain the same symbol. This 7x6 board is being stored in a two dimensional array.

For a piece placed in the board, you'll have 4 sets of checks you must do to see if it was a winning piece:

  1. Check to the left/right for 3 of your pieces.
  2. Check to the upper left/lower right for 3 of your pieces.
  3. Check to the lower left/upper right for 3 of your pieces.
  4. Check above and below for 3 of your pieces.

If we consider X and Y your current board coordinate, wherever I place a piece, these checks correspond to:

  1. X increases/decreases, Y is constant.
  2. As X increases, Y decreases, and vice versa.
  3. As X increases, Y increases, and vice versa.
  4. X is constant, Y increases/decreases.

You should do a lazy check, checking each direction and going the other way as soon as you find something that isn't your piece. If both directions are complete and your total pieces are not 4, that wasn't a winning vector and go on to the next check.

EDIT: Formatting and clarity.

This sounds like a disjoint sets problem but your graph is so small that it would probably be easier to just check all four directions each time like @John Rodgers was talking about. Disjoint sets would probably be a useful thing to learn though. Here's a wikipedia page if you just want to read about it https://en.wikipedia.org/wiki/Disjoint-set_data_structure

I'm trying to make a connect four game. At this point, I am trying to make the game for console interaction only and am having trouble making the grid to look like this format:

Create 7 columns and each containing '.' till the time replaced by either color(just in case the formatting is not shown correctly):

here is what I have so far:

You will want to set NONE to '.', not a space. Then, you could make such a print function for the board:

Used like this:

And when reconstructing your example state:

If you are interested, I made a simple implementation of the whole game based on this idea. You can see it here.
