我尝试创建一个带有网格状标签的 Gui，单击开始按钮，标签将随机填充随机标签中的数字.我无法获得识别随机标签并为其设置文本的代码.标签是在3 X 5"网格的循环中创建的.

I tried to create a Gui with a grid like label, the label will randomly fill with number in random label with a click on the start button. I cannot get the code to recognize the random label and set text to it. The labels are create in a loop for the grid of '3 X 5'.

from tkinter import * import random lbl1 = {} lbl2 = {} lbl3 = {} def fill_auto(): for i in range(1, 6): rd_row = random.randrange(1, 6) rd_col = random.randrange(1, 4) rd_num = random.randrange(1, 16) print(rd_row, rd_col, rd_num) pos = str(rd_col) + str(rd_row) box = 'lbl' + str(pos) print(box) box.config(text=rd_num) root = Tk() root.geometry('+0+0') root.configure(bg='black') for y in range(1, 6): lbl1[str(y)] = Label(root, width=5, relief='solid') lbl1[str(y)].grid(row=y, column=0) lbl2[str(y)] = Label(root, width=5, relief='solid') lbl2[str(y)].grid(row=y, column=1) lbl3[str(y)] = Label(root, width=5, relief='solid') lbl3[str(y)].grid(row=y, column=2) btn = Button(root, text='start', command=fill_auto) btn.grid(row=6, column=1) root.mainloop()

推荐答案

如果你想要一个按钮网格，使用二维列表是有意义的:

If you want a grid of buttons, it would make sense to use a 2d list:

from tkinter import * import random # Create variables for these for the grid width/height width = 3 height = 5 def fill_auto(): for i in range(1, 6): rd_row = random.randrange(0, height) rd_col = random.randrange(0, width) rd_num = random.randrange(1, 16) # Set the label text matrix[rd_row][rd_col].config(text = str(rd_num)) root = Tk() root.geometry('+0+0') root.configure(bg='black') # Helper function to create a label def make_label(x, y): l = Label(root, width=5, relief='solid') l.grid(column=x, row=y) return l; # Using list comprehension to create 2d list matrix = [[make_label(x,y) for x in range(width)] for y in range(height)] btn = Button(root, text='start', command=fill_auto) btn.grid(row=6, column=1) root.mainloop()
