im making the capturing pieces part of the game and it works with the white pawn but for the black pawn it doesnt move it on the square it captured on and if selected after capturing something it captures itself

code to move white pawn:

                if selected_piece.type == "pawn_w":
                    if mousedownY == int(selected_piece.y - 79) and mousedownX == selected_piece.x and not capture:
                        truMove = True
                        selected_piece.starter = False     
                    elif selected_piece.starter:
                        for i in range(len(pieces_list)):
                            if pieces_list[i].square == f'{collumns[mousedownX]}{rows[mousedownY + 79]}':
                                clear_path = False
                                break
                        if clear_path and mousedownY == int(selected_piece.y - 158) and mousedownX == selected_piece.x and not capture:
                            truMove = True
                            selected_piece.starter = False
                    if capture and capture_piece.color != selected_piece.color and mousedownY == int(selected_piece.y - 79) and(mousedownX == selected_piece.x - 79 or mousedownX == selected_piece.x + 79): 
                        capture_piece.taken = True
                        truMove = True
                        selected_piece.starter = False

code to move black pawn:

if selected_piece.type == "pawn_b":
                    if mousedownY == int(selected_piece.y + 79) and mousedownX == selected_piece.x and not capture:
                        truMove = True
                        selected_piece.starter = False  
                    elif selected_piece.starter:
                        for i in range(len(pieces_list)):
                            if pieces_list[i].square == f'{collumns[mousedownX]}{rows[mousedownY - 79]}':
                                clear_path = False
                                break
                        if mousedownY == int(selected_piece.y + 158) and mousedownX == selected_piece.x and clear_path and not capture:
                            truMove = True
                            selected_piece.starter = False
                    if capture and mousedownY == int(selected_piece.y + 79) and(mousedownX == selected_piece.x - 79 or mousedownX == selected_piece.x + 79): 
                        capture_piece.taken = True
                        truMove = True
                        selected_piece.starter = False

code that moves the pieces:

for i in range(len(pieces_list)):
                if pieces_list[i].select and truMove: 
                    moveX(pieces_list[i],pieces_list[i].x, mousedownX)
                    moveY(pieces_list[i],pieces_list[i].y, mousedownY)
                    pieces_list[i].select = False
                    truMove = False
                    break
                elif mousedownX == pieces_list[i].x and mousedownY == pieces_list[i].y:
                    pieces_list[i].select = True
                    break
                elif pieces_list[i].select and not truMove:
                    pieces_list[i].select = False
                    break

i honestly dont know what to try, i cant find what the problem is
