Question

我正在尝试制作一个可以同时录制倒数（并在窗口显示剩余时间）的同时录制麦克风声音的应用。我已经尝试过multiprocessing和threading模块，但是显示倒数和录像（从record.py模块调用）的窗口不会同时运行。
任何人都可以提出任何可行的建议吗？预先感谢。

下面是我的代码：

import tkinter as tk
from tkinter import *
from tkinter import ttk
import time
import record as rc    #record.py is the module to record sound from mic

PRACTICETIME=120

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

        tk.Tk.wm_title(self,"PreSys")

        self.container = tk.Frame(self, height = 1000, width =1000)
        self.container.pack(side="top", fill="both", expand = True)

        self.container.grid_rowconfigure(0, weight=1)
        self.container.grid_columnconfigure(0, weight=1)

        self.frames = {}

        self.create_practicePage(PracticePage)


    def create_practicePage(self,cont):
        frame = PracticePage(self.container, self)
        self.frames[PracticePage] = frame
        frame.grid(row=0, column=0, sticky="nsew")
        self.show_frame(PracticePage)

    def show_frame(self, cont):
        frame = self.frames[cont]
        frame.tkraise()  



class PracticePage(tk.Frame):
    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        self.timeLeft = tk.Label(self,text= "")

        self.timeLeft.pack()

        self.remaining = 0
        self.countdown(120)
        rc.start_record()    #function to record sound


    def countdown(self, remaining = None):
        if remaining is not None:
            self.remaining = remaining

        if self.remaining <= 0:
            self.timeLeft.configure(text="お疲れ様です！")
        else:
            mins, secs = divmod(self.remaining,60)
            mins = round(mins)
            secs = round(secs)
            self.timeLeft.configure(text=str(mins) +"分"+ str(secs) +"秒")
            self.remaining = self.remaining - 1
            self.after(1000, self.countdown)

apps = App()
apps.mainloop()

同时运行两个函数而无需延迟Python
