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，这样按钮不会在同一行上保持打印，但我不确定帧级别是否会保存为self.0，self.1， self.2等......

当我尝试使框架成为网格并调整宽度，高度，行数跨度和列跨度时，我得到了错误（＆＃34;不能使用几何管理器网格。已经有包由＃34管理的奴隶; ）错误来自以下几行：

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，因此每次为其分配新值时，都会丢失现有值。最后它只包含分配给它的最后一个值。还

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

创建31 * 31个按钮（超过900个按钮）。在学习的过程中，坚持使用程序中的所有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()

如何使用.pack（）或.grid（）在框架中创建按钮网格？
