python

Question

我目前正在研究的Python程序是一种改变颜色的记忆游戏，你可以重复它。此时它还没有完成，但我遇到的问题是写入课堂的时间函数。它发生在颜色切换程序之后，但在颜色切换发生之前仍然发生时间延迟。因此，我需要一个校正，使得在每次单独的颜色切换后发生延迟，并且仅在发生相同错误后尝试使用datetime

time.sleep(2) 

以下是代码：

from tkinter import *
from random import *
from tkinter import font
from time import*

    def __init__(self,master):
        self.bluecolour = "#103"

        self.lightgreen = "#172"
        self.redcolour = "#701"

        self.yellowcolour = "#987"

        self.master = master
        self.master.title("Simon Says")

使用tkinter时，使用time.sleep(...)不起作用。如果您想延迟，请使用after（）。要使用after命令，请使用tk模块并在其后面放置时间和功能。这是一个例子：

root = Tk()

def doSomething():
    something = 0

root.after(1000, doSomething)

时间以毫秒为单位，例如1000ms = 1秒。 希望我能帮忙:)。
