我有很长一段代码。我不想把它全部粘贴在这里，所以让我解释一下我在这里想要完成的事情。基于用户提供的数字，我想创建许多文本框，然后获取输入到该文本框中的内容并将其插入到字典中。我尝试过这几种方法，但却无法让它正常工作。该列表为空或仅包含最后一个文本框作为每个键的值。
def multiple_choice():
def add():
top.destroy()
top = Tk()
top.title("Add Question")
w = 800
h = 800
ws = top.winfo_screenwidth()
hs = top.winfo_screenheight()
x = (ws/2) - (w/2)
y = (hs/2) - (h/2)
top.geometry('%dx%d+%d+%d' % (w, h, x, y))
question = Label(top, text="Question to be asked?", font = "Times 14 bold", fg = "blue")
question.grid(row = 2, column = 4)
questionText = Text(top, borderwidth = 5, width=50,height=5, wrap=WORD, background = 'grey')
questionText.grid(row = 3, column = 4)
numQuestions = Label(top, text = "Number of answer choices?", font = "Times 14 bold", fg = "blue")
numQuestions.grid(row = 4, column=4)
num = Entry(top, bd = 5)
num.grid(row=5, column = 4)
answerList = {}
def multiple():

title.grid(row = 0, column = 2)
qtext = "Question text will read: "
ques = Label(preview, text = qtext)
ques.grid(row=1, column = 2)
ques2 = Label( preview, text = questionText.get("1.0",END))
let = 'A'
i = 1
for word in answerList:
prev = let + ": " + word
ans = Label(preview, text = prev)
ans.grid(row=1+i, column = 2)
let = chr(ord(let) + 1)
answerCor = "The correct answer(s): "
a = Label(preview, text = answerCor)
a.grid(row=4, column = 2)
b = Label(preview, text = cor.get)
b.grid(row=5, column = 2)
if num.get().isdigit():
number = int(num.get())
AnswerChoices = Label(top, text = "Answer Choices?", font = "Times 14 bold", fg = "blue")
AnswerChoices.grid(row = 6, column=4)
i = 0
let = 'A'
while i < number:
letter = Label(top, text = let)
letter.grid(row = 8+(i*4), column = 3)
answer = Text(top, borderwidth = 5, width=50, height=3, wrap=WORD, background = 'grey')
answer.grid(row = 8+(i*4), column = 4)
answerList[let] = answer.get("1.0",END)
i = i+1
let = chr(ord(let) + 1)
print answerList
correct = Label(top, text = "Correct Answer(s) (seperated by commas)",
font = "Times 14 bold", fg = "blue")
correct.grid(row =99 , column=4)
cor = Text(top, borderwidth = 5, width=50, height=3, wrap=WORD, background = 'grey')
cor.grid(row=100, column = 4)

E1.grid(row=0, column=3)
name_file = E1.get()
name_file = name_file.replace(" ", "")
name_file = name_file + ".txt"
with open(name_file,"w") as data:

quiz.mainloop()
我正在尝试使用这段代码创建字典：
i = 0
let = 'A'
while i < number:
letter = Label(top, text = let)
letter.grid(row = 8+(i*4), column = 3)
answer = Text(top, borderwidth = 5, width=50, height=3, wrap=WORD, background = 'grey')
answer.grid(row = 8+(i*4), column = 4)
answerList[let] = answer.get("1.0",END)
i = i+1
let = chr(ord(let) + 1)
我甚至尝试在预览函数中放置一个循环，但是当最后一个框是字典中包含的唯一值时。任何想法将不胜感激
答案 0 :(得分：0)
请参阅下面的我所记录的片段，其中说明了这一点：
from tkinter import *
class App:
def __init__(self, root):
self.root = root
self.entry = Entry(self.root) #entry to input number of entries later
self.button = Button(self.root, text="ok", command=self.command) #calls command to draw the entry boxes
self.frame = Frame(self.root)
self.entry.pack()
self.button.pack()
self.frame.pack()
def command(self):
self.frame.destroy() #destroys frame and contents
self.frame = Frame(self.root) #recreates frame
self.text = [] #empty array to store entry boxes
for i in range(int(self.entry.get())):
self.text.append(Entry(self.frame, text="Question "+str(i))) #creates entry boxes
self.text[i].pack()
self.done = Button(self.frame, text="Done", command=self.dict) #button to call dictionary entry and print
self.done.pack()
self.frame.pack()
def dict(self):
self.dict = {}
for i in range(len(self.text)):
self.dict.update({self.text[i].cget("text"): self.text[i].get()})
#the above line adds a new dict entry with the text value of the respective entry as the key and the value of the entry as the value
print(self.dict) #prints the dict
root = Tk()
App(root)
root.mainloop()
上面询问用户他们想要创建多少个entry小部件，使用这些frame小部件填充entry，然后遍历包含它们的list按下button，为每个dictionary窗口小部件添加新的entry条目，其中key的{{1}}是属性dict对于每个text，entry的{{1}}是value的{{1}}。
