我想提出一个单独的问题,它不会偏离原始主题(考虑到由于我对论坛规则缺乏关注而产生的反对意见)
出于某种奇怪的原因,我创建了一个名为def Questionnaire():
quiz_page = Tk()
quiz_page.title('Questionnaire')
quiz_page.geometry('600x350')
greet = Label(quiz_page, text='Welcome to the questionnaire! You will '
'answer a few questions to produce a result '
'for both you and your teacher to see!')
greet.grid(row=0,column=0)
的新窗口:
def student_menu():
#student_login.destroy()
student_page = Tk()
student_page.title('Hello student')
student_page.geometry('300x130')
Welcome_msg = Label(student_page, text='Welcome').pack()
Questionnaire = Button(student_page,text='Quiz',command=Questionnaire).pack()
View = Button(student_page,text='View',command=view).pack()
然后我将该功能调用到学生登录页面。
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Users\Hassan Nur\AppData\Local\Programs\Python\Python37-32\lib\tkinter\__init__.py", line 1705, in __call__
return self.func(*args)
File "C:\Users\Hassan Nur\Documents\Python - Programming Project\Project\Python Project\Python Project.py", line 78, in student_confirm
student_menu()
File "C:\Users\Hassan Nur\Documents\Python - Programming Project\Project\Python Project\Python Project.py", line 107, in student_menu
Questionnaire = Button(student_page,text='Quiz',command=Questionnaire).pack()
UnboundLocalError: local variable 'Questionnaire' referenced before assignment
但是当我登录该应用程序时,出现一个没有按钮的窗口,并且出现此错误。
import { createBrowserHistory } from "history";
如果可能(甚至有资格),请您帮忙?
答案 0 :(得分:0)
特别感谢martineau和jasonharper! 发现问卷已被定义为一个按钮,如您所见...
def student_menu():
#student_login.destroy()
student_page = Tk()
student_page.title('Hello student')
student_page.geometry('300x130')
Welcome_msg = Label(student_page, text='Welcome').pack()
Question = Button(student_page,text='Quiz',command=Questionnaire).pack()
View = Button(student_page,text='View',command=view).pack()
我只需要重命名其中一个按钮
