Question

我正在Tkinter Python上创建一个Sudoku GUI。几乎完成但我想要发生的是当你点击一个按钮（9x9网格中的一个正方形）时，它是一个0（网格中的一个数字，以前没有设置在开头（一个空的间隙）我已经指定为红色0））它增加1.所以如果你点击这4次它就变成了数字4.（你可能想要主要参考----主要代码---在底部）

Answer 1

您必须在按钮回调中修复lambda值，这是我添加到代码中的主要更改。所有其他编辑主要是为了使代码更清晰，并删除所有不必要的部分。

回到主页消息ist，如果你没有修复传递给lambda函数的值，那么你基本上总是使用Button(command=...)的回调函数的最后一个迭代器值。添加row=rowindex,...会强制Python在创建按钮时回顾/保存值。

import numpy as np

hardUnsolved=np.array([[8,0,0,0,0,0,0,0,0],...])

def btnCommand(row, col, x):
    x += 1
    hardUnsolved[row][col] = x
    createGrid()

#-----------------------------MAIN CODE------------------
def createGrid():
    for rowindex in range (9):
        for colindex in range (9):
            if ((rowindex in (0,1,2,6,7,8) and colindex in (3,4,5)) or \
                rowindex in (3,4,5) and colindex in (0,1,2,6,7,8))):
                colour='blue'
            else:
                colour='white'

        x=hardUnsolved[rowindex][colindex]

        if x==0:
            colourTxt='red'
        else:
            colourTxt='black'

        btn=Button(frame, width=4, height=3, bg=colour, text=x, fg=colourTxt, 
            command=lambda row=rowindex, col=colindex, x=x: btnCommand(row, col, x))
        btn.grid(row=rowindex, column=colindex, sticky=N+S+E+W)
        btn.grid(row=rowindex, column=colindex, sticky=N+S+E+W)

    mainloop()

createGrid()

编辑：我还导入了numpy，以便为您的网格分配值更直观，更干净。

Answer 2

在下面的代码中，按钮循环显示小数字，除了0，基本上是数字，对于widget的文本：

import tkinter as tk


def cycle(widget):
    widget['text'] = (widget['text'] % 9) + 1

root = tk.Tk()

btn = tk.Button(root, text=1)
btn['command'] = lambda widget=btn: cycle(widget)
btn.pack()

root.mainloop()
