You can use the __str__ method to print your board:
Once the game works the way you need, you can easily build a GUI with tkinter around it, in a separate set of files.

In the following example, I am using a list of lists to represent the board. I changed the settings to represent the traditional 6 rows and 7 columns of connect-4.

QUESTION

How to append strings from a loop to a single output line?

Asked 2020-Jun-07 at 13:41

So I am trying to make a text-based game of connect-4 for the purposes of better understanding Python and how it actually works.

Short version

How can I append printed text from every run-through of a while loop to a print output that exists just before the while loop
Out of the two methods seen below (The work in progress and the current successfully working one) which is a better practice of executing the desired output?

Long version

I am trying to use a looping system to print out an array in an evenly spaced and aesthetically pleasing format after every turn is taken, so users have clear feedback of what the current board looks like before the next turn is taken. To do this I want to be able to have lines of code that are as small as possible for making it easier to read the code itself. Although this might not be the best practice for executing this scenario I want to understand this way of coding better so I could apply it to future projects if need be.

In terms of the actual execution, I am trying to use a while loop to append 7 positions of an array one after another in the same output line for array positions that are in the same row. after this, I want to print the next row on the line below the previous one as seen in the code below "Desired output".

Thank you in advance for your answers, suggestions and comments.

Work in progress

The simple fix is to use end=' ' on the print inside the while loop on j and then add a print() after it:

QUESTION

What is going wrong with my Minimax Algorithm?

Asked 2020-May-05 at 17:35

I tried to make a MiniMax AI using a tutorial,

The AI doesn't work and just goes on the bottom row and build up each time, reporting a column index of 0, 1, 2, 3, 4, 5, 6 and then for the next row and so on. The only thing I managed to find a lot different in the code output compared to mine and the tutorials working version was the depth of the minimax algorithm as it goes along. Where this was the depth of the working one as it recurred, and this was the depth of my one (it was longer than this but my console didn't keep all of it). I've tried a lot of things to get it working including reworking the board system to multiple lists inside a list and many other things like deleting some parts of the code and reworking scores but it doesn't seem to change.

My minimax function is:

ANSWER

Answered 2020-May-05 at 17:35

The board is passed passed to your minimax function as a parameter node, but inside the function you use board.

Reference program: def minimax(board, depth, alpha, beta, maximizingPlayer):

Your program: def minimax(node, depth, alpha, beta, maximizingPlayer):

Your recursive minimax function is therefore not working as expected.

Edit: To fix this replace board inside minimax with node (don't change node in the function definition to board)

Edit 2: Also check the function scorePos - you have a hardcoded computerDisc instead of using the function argument.

Edit 3: Additionally, other helper functions like isBoardFull() and isSpaceFree() should operate on the board copy, not the global variable.

QUESTION

presenting menus in tkinter

Asked 2020-Feb-19 at 14:24

I'm writing a connect-4 game with Tkinter, and I would to present several menu options to the user during the course of the game.

The problem is that the menus tend to be presented together, as in the piece of code below. For example, in present_player_choice(), I'd like to present a menu for playerA, get an answer, and then present a menu for playerB. This is not that crucial here, but it's a problem I keep running across.

after() does not seem to be the answer, as I do not want the menu to disappear after a certain space of time, but rather to disappear after the user has submitted an answer.

Also: In writing an 'ok' button for the menu, I've used 'quit.' But quit closes the entire widget! I want the gui to continue, and simply the menu to close, not the entire GUI!

I know these questions sound rather clueless, but I've been working on this for a while and am genuinely confused. Thanks in advance for any help.

The quickest way to do this is to add a Frame to your class that we can use to reset the content and then move the call for player B into a condition in the assign_player method to update the frame for player B when a selection is chosen.

You may also want to add tristatevalue=0 to your radio buttons so that there is no default selection.

QUESTION

Connect4 winning algorithm in a given format

Asked 2019-Jun-10 at 17:13

Let us say the status of a Connect4 game is stored like 12341, which means player 1 dropped his ball in position 1, and then player 2 in position 2, player 1 in position 3, player 2 in position 4 and player 1 in position 1 again.

In this format, is there an algorithm that can know if a game is won, in a way that is better than converting into a 2-d matrix and using the algorithms that is already listed in SO, like Connect 4 check for a win algorithm?

...

ANSWER

Answered 2019-Jun-10 at 17:13

The characteristics of the game connectivity are such that the most effective method is to convert to the 2D paradigm to check for wins. The fastest method for most people is to check the current move in all directions, to see whether it just created a win.

You can somewhat improve the "intelligence" of the checking, by keeping a list of "live" lines -- possible future wins -- and checking to see which ones the most recent move extends or blocks.

Note that this is a less obvious approach for both coding and maintenance. Also, it's slower than checking the current move in all directions. It's really useful only if used to create an automatic player (AI).

ANSWER

Answered 2019-Jan-14 at 16:15

Under the mantra of c++ only pay for what you use, there is no garbage collection. This means that you need to manage memory yourself. In this specific case you have 2 options:

Don't make game with new. Depending on your application, just using Game game; may be enough.
If you really need to new Game, wrap the new in an RAII (Resource acquisition is initialization) idiom type. You can leverage c++ smart pointers:

auto game_ptr = std::make_unique();

When the scope of the unique_ptr ends, the memory that it contains will be automatically released.

Find diagonals in a Python matrix using lists

Asked 2018-Nov-22 at 12:55

I'm trying to code the game connect-4, and there is a part of my code in which i try to find in a 7x6 matrix, diagonals of 4 ones in a row or 4 2s in a row. This part of my code does not work i tried everything I was able to. And sometimes it detects that there is a 4 1s or 4 2s diagonal where is not. I created the matrix puting a 7 zero list in each position of a 6 zeros lists. I'm trying to do it using only lists functions, i cant use the numpy library or similar. Okay, in this part of the code I'm trying to find if in each possible diagonal of the matrice there are 4 zeros in a row. PD: I'm only trying to find the diagonals that go from left to right ATM.

The variables row and col are assigned by the for loop with the values of the items in the lists, not the indices of the lists. You should use the range generator instead if you want to make row and col indices:
