为什么我的tkinter GUI在程序结束时冻结

Question

我很难让它正常工作，有人能帮我吗？我的窗口在程序结束时会冻结，因为它本应该允许另一个输入。整个程序都粘贴在下面，我到处找帮助，都被卡住了。很抱歉代码太粗糙了，我一直在组合不同的片段，希望好运。

使用python 3.8.1

import time
from tkinter import *
from random import randint
answers = ["It is almost certain",
"It is decidedly so",
"Without a doubt",
"Yes definitely",
"You may rely on it",
"As I see it, yes",
"Most likely",
"Outlook good",
"Yes",
"Signs point to yes",
"Reply hazy try again",
"Ask again later",
"Better not tell you now",
"Cannot predict now",
"Concentrate and ask again",
"Don't count on it",
"My reply is no",
"My sources say no",
"Outlook not so good",
"Very doubtful"]
queries = []
repeat = "You already asked that question."
think = "thinking..."
sorry = "Sorry, I didn't understand you. Exiting..."
yes = ["YES", "yes", "Yes", "ya", "Ya", "YA", "y", "Y"]
no = ["NO", "no", "No", "nah", "Nope", "n", "N"]

def question():
query = e1.get()
print(think)
time.sleep(2)
if query not in queries:
queries.append(query)
else:
print(repeat)
print(answers[randint(0,19)])
restart()
def restart():
reply = input("Thanks for playing. Do you want to ask another question? ")
if reply in yes:
e1.delete(0, END)
question()
elif reply in no:
exit()
else:
print(sorry)
exit()
root = Tk()
root.title("Magic 8 Ball")
logo = PhotoImage(file="Blank.png")
w1 = Label(root, image=logo).pack(side="top")
w2 = Label(root,justify=CENTER,pady=10,padx=20,font="Verdana 12 bold",text="Hello! Welcome to the Magic 8 Ball.").pack(side="top")
w3 = Label(root,justify=LEFT,font="Verdana 10",text="Enter your question here: ").pack(side="top")

e1 = Entry(root,width=50)
e1.pack(side="top")

b1 = Button(root,width=10,text="Submit",command=question).pack(side="top")
w4 = Label(root,justify=LEFT,pady=20,font="Verdana 10",text="Answer:").pack(side="top")

root.mainloop()

您不应该在GUI应用程序中混合控制台input。改为使用tkinter.messagebox.askquestion()：

from tkinter.messagebox import askquestion
...
def restart():
reply = askquestion("Confirm", "Thanks for playing.nDo you want to ask another question?")
if reply in yes:
e1.delete(0, END)
#question()
elif reply in no:
exit()
else:
print(sorry)
exit()
