Creating a virtual representation of the board

How would you represent a Connect 4 board? There are two commonly used methods for representing the Connect 4 board, along with the game state. Let's take a look:

• Long, human-readable form: In this form, the rows and columns of the board are displayed on the x and y axes and the markers of both the players are displayed as x and o, respectively (or any other suitable characters). This may look as follows:

  |1 2 3 4 5 6 7 --+-------------- 1|. . . . . . . 2|. . . . . . . 3|. . . . . . . 4|. . . . o x . 5|x o x . o o . 6|o x x o x x o

This form is, however, a bit lengthy and not very computationally friendly. 

• Computationally efficient form: In this form, we store the board as a 2D NumPy array: ...
