我正在嘗試實作一個鋼琴游戲。規則很簡單：播放一個音符，5 秒后顯示答案。問題是我希望用戶能夠在程式等待這 5 秒時播放音符。現在，當游戲模式的行程開始時，程式會創建一個新的 GUI 視窗。
游戲模式類：
from multiprocessing import Process
import random
import time
class Practice(Process):
def __init__(self, keys, rounds = 5):
super(Process, self).__init__()
self.rounds = rounds
self.keys = keys
def run(self):
for i in range(3):
answer = self.__random_key()
answer.play()
time.sleep(3)
print("woke up")
self.show_answer()
def show_answer(self, answer):
print(f"Answer is: {answer.name}")
def __random_key(self):
return self.keys[random.randint(0, len(self.keys) - 1)]
鋼琴鍵類：
import asyncio
import copy
import time
from tkinter import Button
from pygame import mixer
class PianoKey():
def __init__(self, master, note = None, octave = None, color = None):
self.master = master
self.note = note
self.color = color
self.octave = octave
self.name = f"{note}{octave}"
self.button = Button(self.master, bg = color, command = lambda : self.play())
def get_piano_button(self):
return self.button
def empty_copy(self):
button = self.button
self.button = None
result = copy.copy(self)
self.button = button
def change_color(self, color):
self.button.config(bg = color)
def play(self):
path = "PATH_OF_NOTES_FOLDER"
print(f"played {self.name}")
# mixer.music.load("B3.mp3")
# mixer.music.play()

uj5u.com熱心網友回復：
使用root.after()方法。它可以延遲，time.sleep()但也可以在超時結束時呼叫函式。這樣，用戶可以在程式等待的同時彈奏鋼琴音符。這是一個關于root.after().
