问题描述
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()
