def addToBoard(board, piece): # fill in the board based on piece's location, shape, and rotation for x in range(TEMPLATEWIDTH): for y in range(TEMPLATEHEIGHT): if PIECES[piece['shape']][piece['rotation']][y][x] != BLANK: board[x + piece['x']][y + piece['y']] = piece['color']

The board data structure is a data representation for the rectangular space where pieces that have previously landed are tracked. The currently falling piece is not marked on the board data structure. What the `addToBoard()`

function does is takes a piece data structure and adds its boxes to the board data structure. This happens after a piece has landed.

The nested `for`

loops on lines 3 [376] and 4 [377] go through every space in the piece data structure, and if it finds a box in the space (line 5 [378]), it adds it to the board (line 6 [379]).
