How to draw multiple images in Python using tkinter?

Question

Python

The essence of the project is chess. The first stage, that is, the drawing of the board, was successful:

Next, you need to draw the figures, 80x80 pictures of which I threw into the root folder.
The pieces must be drawn based on the cells of the pieces matrix , which at the beginning of the game

where the first letter (b/w) is the color and K, Q, R, B, N or P is the piece (or pawn) .

Actually, the drawing of the figures looks like this:

for i in range(8):
        for j in range(8):
            x = 50 + i * 80     # 50 - отступ, 80х80 - размер клетки
            y = 50 + j * 80
            if pieces[i][j] == 'wP':
                img = PhotoImage(file="WhitePawn.png")
            elif pieces[i][j] == 'wK':
                img = PhotoImage(file="WhiteKing.png")
            elif pieces[i][j] == 'wQ':
                img = PhotoImage(file="WhiteQueen.png")
            elif pieces[i][j] == 'wR':
                img = PhotoImage(file="WhiteRook.png")
            elif pieces[i][j] == 'wN':
                img = PhotoImage(file="WhiteKnight.png")
            elif pieces[i][j] == 'wB':
                img = PhotoImage(file="WhiteBishop.png") 
            elif pieces[i][j] == 'bP':
                img = PhotoImage(file="BlackPawn.png")
            elif pieces[i][j] == 'bK':
                img = PhotoImage(file="BlackKing.png")
            elif pieces[i][j] == 'bQ':
                img = PhotoImage(file="BlackQueen.png")
            elif pieces[i][j] == 'bR':
                img = PhotoImage(file="BlackRook.png")
            elif pieces[i][j] == 'bN':
                img = PhotoImage(file="BlackKnight.png")
            elif pieces[i][j] == 'bB':
                img = PhotoImage(file="BlackBishop.png")
            canvas.create_image(x,y, anchor=NW, image=img)
            print(x, ' ', y, ' ', img) #отладка
            img = ''

Pictures are in place:

but nothing is drawn. Moreover, if you try to draw any one figure, there are no problems.

Actually, the question is what to do? How to draw 32 pictures?

Answer 1

all because you have one img variable and you need an array equal to the number of cells - 8*8.
or pass the file name and not the image object.
The problem is that the variable limits the number of possible objects to 1, since a reference to the object is passed.
