python - 需要帮助每分钟更新一个 tkinter 函数

Question

问题:

我正在尝试使用 tkinter 创建一个程序来显示每日棒球比赛、开始时间和实时比分。问题在于实时分数，因为我无法找到如何集成更新保存当前分数的函数(daily_games)的方法。

我只编程了几个月，所以我的代码可能到处都是......对于这么长的帖子也感到抱歉。

到目前为止我已经尝试过:我尝试过使用 after() 和 tkinters update() 但我不确定如何集成它。

代码:

# when called this method populates Start page with links, times, scores, and game status
def daily_games(self):
    streams = stream_links.today_streams()
    row = 5
    for game in streams:
        team_1 = game[1]
        team_2 = game[2]

        logos = team_logos(team_1, team_2)
        logo = logos[0]
        logo2 = logos[1]

        # assigns team one logo
        t1_logo = tk.Label(self, image=logo)
        t1_logo.image = logo
        t1_logo.grid(column=1, row=row, sticky='NSEW')

        # assigns team two logo
        t2_logo = tk.Label(self, image=logo2)
        t2_logo.image = logo2
        t2_logo.grid(column=4, row=row, sticky='NSEW')

        # links to streams
        lbl = tk.Label(self, text=team_1 + " vs " + team_2, fg="blue", cursor="hand2", font=AVG_FONT)
        lbl.grid(column=3, row=row, sticky='NSEW')
        assign_link(lbl, game[0])

        # uses mlbgame package to get gametimes, status, and scores
        game_info = matchup_info(team_1)
        game_status_lbl = tk.Label(self, text=game_info[1], font=AVG_FONT)
        game_status_lbl.grid(column=5, row=row, sticky='NSEW')
        score_lbl = tk.Label(self, text=game_info[2] + " - " + game_info[3], font=AVG_FONT, padx=10, pady=10)
        score_lbl.grid(column=6, row=row, sticky='NSEW')
        game_start_lbl = tk.Label(self, text=game_info[0], font=AVG_FONT, padx=10, pady=10)
        game_start_lbl.grid(column=0, row=row, sticky='NSEW')

        row += 2

    return row


# method works with mlb_data to find info on game matchups and returns desired data
def matchup_info(team):
    # assigning start times/ status/ scores
    game_start = mlb_data(DATE, names_dict[team])[0]
    status = mlb_data(DATE, names_dict[team])[1]
    t1_score = str(mlb_data(DATE, names_dict[team])[2])
    t2_score = str(mlb_data(DATE, names_dict[team])[3])

    return game_start, status, t1_score, t2_score


class BaseballStreamsApp(tk.Tk):
    def __init__(self, *args, **kwargs):

        tk.Tk.__init__(self, *args, **kwargs)

        tk.Tk.iconbitmap(self, "C:\\Users\\\\PycharmProjects\\baseball_streams\\bbstreams\\mlb_logos\\MLB.ico")
        tk.Tk.wm_title(self, "MLB Streams")

        container = tk.Frame(self)
        container.pack(side="top", fill="both", expand= True)
        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)

        frame = StartPage(container, self)

        self.frames[StartPage] = frame

        frame.grid(row=0, column=0, sticky="nsew")

        self.show_frame(StartPage)

    def show_frame(self, cont):

        frame = self.frames[cont]
        frame.tkraise()


class StartPage(tk.Frame):
    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        title_lbl = tk.Label(self, text="MLB Streams " + str(date.today()), font=LARGE_FONT)
        time_lbl = tk.Label(self, text="Time", font=AVG_FONT)
        game_lbl = tk.Label(self, text="Game", font=AVG_FONT)
        score_lbl = tk.Label(self, text="Score", font=AVG_FONT)
        status_lbl = tk.Label(self, text="Status", font=AVG_FONT)

        title_lbl.grid(column=2, row=0, columnspan=2, pady=10, padx=10, sticky='NSEW')

        # constant mlb network stream link
        mlb_network = tk.Label(self, text="MLB Network", font=AVG_FONT, fg="red", cursor="hand2")
        mlb_network.grid(column=4, row=0, sticky='NSEW')
        mlb_network.bind("<Button-1>",
                         lambda event:webbrowser.open_new("http://.net/game-1-.html"))

        configure(self, daily_games(self), 7)


app = BaseballStreamsApp()
app.mainloop()

<小时/>

目前，当我运行函数 (daily_games) 时，我想要自动更新的函数最初在 (StartPage) 类和这一行的 _init_ 函数中执行

configure(self, daily_games(self), 7)

我希望有一种方法可以每分钟或在我指定的时间自动运行 (daily_games) 函数。

担忧:

假设我能够自动运行该函数，我的问题是，程序是否会继续在以前的标签上写入 tkinter 标签，导致我的程序给计算机带来不必要的负载？

如果是这样，我应该如何删除以前的标签。

提前致谢!再次对这么长的帖子表示歉意

我在这里工作就是现在的样子

class BaseballStreamsApp(tk.Tk):
    def __init__(self, *args, **kwargs):

        tk.Tk.__init__(self, *args, **kwargs)

app.mainloop()

这似乎有效......但不确定它的效率如何
