如何使用 .pack() 或 .grid() 在框架中创建按钮网格？

Question

from tkinter import *
from random import *

class Game:
    def __init__(self):
        self.root = Tk()

        self.frame1 = Frame(self.root, width = 1055, height = 30)
        self.frame1.pack()

        self.frame_lvl = Frame(self.root, width = 1055, height = 1055)
        self.frame_lvl.pack()

        for frame_lvl in range(0,31):
            self.frame_lvl = Frame(self.root)
            self.frame_lvl.pack(side = BOTTOM)
        for i in range(0,31):
            for j in range(0,31):
                button = Button(self.i, width = 30, height = 30, padx = 2, pady = 2)
                button.pack(side = LEFT)

        self.root.mainloop()

app = Game()

所以我尝试创建一个新的帧级别，这样按钮就不会一直打印在同一行，但我不确定帧级别是否会保存为 self.0、self.1、self.2、等等……

当我尝试将框架设置为网格并调整宽度、高度、行跨度和列跨度时，出现错误（“不能在内部使用几何管理器网格。它已经有由包管理的从属”）错误来自这些行：

self.frame2 = Frame(width = 1055, height = 1055)
self.frame2.grid(columnspan = 30, rowspan = 30)

任何建议。

请注意，只有一个 self.frame_lvl，因此每次为它分配一个新值时，都会丢失现有值。最后，它将只包含分配给它的最后一个值。还有

for i in range(31):
    for j in range(31):

创建 31*31 个按钮（超过 900 个按钮）。在你学习的时候，坚持在程序中使用所有 grid() 或 all pack()，直到你学会如何混合这两者。使用 grid() 创建 3 行，每行 5 个按钮

from tkinter import *
from functools import partial

class Game:
    def __init__(self):
        self.root = Tk()

        self.frame1 = Frame(self.root, width = 900, height = 30)
        self.frame1.grid()

        self.label=Label(self.frame1, text="")
        self.label.grid(row=0, column=0, columnspan=5)

        ## save each button id in a list
        self.list_of_button_ids=[]
        for ctr in range(15):
            ## use partial to pass the button number to the
            ## function each time the button is pressed
            button = Button(self.frame1, text=str(ctr), width = 20,
                            height = 20, padx = 2, pady = 2,
                            command=partial(self.button_callback, ctr))
            this_row, this_col=divmod(ctr, 5)
            ## the label is in the top row so add one to each row
            button.grid(row=this_row+1, column=this_col)

            ## add button's id to list
            self.list_of_button_ids.append(button)
        self.root.mainloop()

    def button_callback(self, button_num):
        """ display button number pressed in the label
        """
        self.label.config(text="Button number %s and it's id=%s"
                   % (button_num, self.list_of_button_ids[button_num]))


app = Game()
