为什么我的tkinter代码在我的ttsx3代码之前没有执行

问题描述

这是我的代码：

from tkinter import*
import pyttsx3
import datetime


win=Tk()
win.configure(background="black")
win.geometry("500x700")
win.resizable(width=False,height=False)

#-----------------------------------------------------------------------------------------------------------------------------------------------
sys=pyttsx3.init()
voice_id="HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Speech\\Voices\\Tokens\\TTS_MS_Cortana"
sys.setProperty("voice",voice_id)
def say(audio):
    sys.say(audio)
    sys.runAndWait()
    return

def wishme():
    hour = int(datetime.datetime.Now().hour)
    if hour>=0 and hour<12:
        t1=Label(win,text="Good Morning,sir",font=("calibri",25),bg="black",fg="light green").grid(column=0,row=0,sticky=W)
        t2=Label(win,text="What can I do for you today?",18),row=2,sticky=W)
        say("Good Morning,sir.")
        say("what can I do for you today?")
        
    elif hour>=12 and hour<18:
        t1=Label(win,text="Good Afternoon,15),sticky=W)
        say("Good Afternoon,sir.")
        say("what can I do for you today?")
        
    elif hour>=18 and hour<21:
        t1=Label(win,text="Good Evening,sticky=W)
        say("Good evening,sir.")
        say("what can I do for you today?")
    else:
        t1=Label(win,text="Hello,sticky=W)
        say("Hello,sir.")
        say("what can I do for you today?")

wishme()

win.mainloop()

我想做的是先打开我的tkinter窗口，然后祝我早，晚等。但是我希望我先打开tkinter窗口。有人可以帮我吗？

解决方法

首先，设置所有标签，然后在say()函数中进行对wishme()函数的所有调用。 tkinter的win.after(100,wishme)将在主循环100毫秒后运行wishme()。

def wishme():
    hour = int(datetime.datetime.now().hour)
    if hour>=0 and hour<12:
        say("Good Morning,sir.")
    elif hour>=12 and hour<18:
        say("Good Afternoon,sir.")
    elif hour>=18 and hour<21:
        say("Good evening,sir.")
    else:
        say("Hello,sir.")
    say("what can I do for you today?")


win.after(100,wishme)
win.mainloop()

,

它是这样说的：

Traceback (most recent call last):
  File "c:/Python37/win2.py",line 51,in <module>
    wishme()
  File "c:/Python37/win2.py",line 40,in wishme
    t1=Label(win,text="Good Evening,sir",font=("calibri",25),bg="black",fg="light green").grid(column=0,row=0,sticky=W)
  File "C:\Python37\lib\tkinter\__init__.py",line 2766,in __init__
    Widget.__init__(self,master,'label',cnf,kw)
  File "C:\Python37\lib\tkinter\__init__.py",line 2299,in __init__
    (widgetName,self._w) + extra + self._options(cnf))
_tkinter.TclError: can't invoke "label" command: application has been destroyed
