How to create a python game board using 2d array?-CodePudding

I am very new to Python but I am trying to create a text based game board for dots and boxes. I am not too sure where to start with the code yet but my idea is to get a desired output of a 3X4 board like this:

(1,1) (1,2) (1,3) (1,4)

(2,1) (2,2) (2,3) (2,4)

(3,1) (3,2) (3,3) (3,4)

The player input I am planning for later is, for example with input of (1,3)(2,3) it would draw a line between the two and so on.

(1,1) (1,2) (1,3) (1,4)
                    |
(2,1) (2,2) (2,3) (2,4)

(3,1) (3,2) (3,3) (3,4)

Can anyone help me with understanding how to draw the board? I am new to python data types and data structures but reading up on it makes me think I need to be creating a 2d array. Any help is greatly appreciated, thanks!

There are lots of options depending on exactly what state you need to store. One way is to store the links between cells as tuples in a set, and check for these when drawing the board.

width = 4
height = 3
links = set()

def draw_board():
    for row in range(1, height 1):
        for col in range(1, width 1):
            if ((row, col), (row, col 1)) in links:
                sep = "-"
            else:
                sep = " "
            print((f"({row},{col}) {sep} "), end="")
        print()
        for col in range(1, width 1):
            if ((row, col), (row 1, col)) in links:
                print("  |     ", end="")
            else:
                print("        ", end="")
        print()

draw_board()
# add some links to test
links.add(((1,2),(1,3))) 
links.add(((2,2),(3,2)))
links.add(((2,4),(3,4)))
draw_board()

Actually you don't need to specify two input one is enough .Here is the code that allow you to draw the board :

myBorad = [[str((i,j)) for j in range(1,5)] for i in range(1,4)]
for i in range(1,4,2):
    myBorad.insert(i,["    " for j in range(4)])

a,b = [int(i) for i in input().split(" ")]

myBorad[a][b]=" |"

for i in myBorad:
    print(" ".join(i))

Input:

1 3

Output :

(1, 1) (1, 2) (1, 3) (1, 4)
                |
(2, 1) (2, 2) (2, 3) (2, 4)

(3, 1) (3, 2) (3, 3) (3, 4)

Note : In order to make it more active you could add a loop that ask for the input and each time you print out the board because all the previous result are already saved in the list myBord
