如何在一个函数下全部导入 [英] How to import all under a function

问题描述

我有一个登录屏幕，登录后将进入带两个按钮的页面.食堂页面按钮和管理页面按钮.

I have a login screen that once logged in will take me to a page that has two buttons. Canteen page button, and admin page button.

我的第一个问题是，一旦我按按钮打开食堂页面，该页面内的所有内容似乎都无法正常工作.我无法从模块导入所有内容，但我必须从Canteen导入*". 我的第二个问题与第一个问题相同，只是在管理"屏幕上.

my first problem is that once I open my canteen page by pressing the button everything that's inside this page doesn't seem to be working. I assume I have to 'import * from Canteen' although I cant import all under a module. my second problem is the same as the first just with my Admin screen.

def adminpage():
    import Admin

def canteenpage():
    import Canteen

find_user = ('SELECT * FROM user WHERE username = ? and password = ?')
        c.execute(find_user,[(self.username.get()),(self.password.get())])
        result = c.fetchall()
        if result:
            root=Tk()
            root.geometry("400x400")
            root.title("Select Page")
            Label(text = "welcome to the dashboard").pack()
            Button(root, text = "Canteen Page",command=canteenpage).pack()
            Button(root, text = "Admin Page",command=adminpage).pack()

推荐答案

您应将所有代码放在另一个模块中(在您的情况下为"Admin"和"Canteen").那对你有用.

You should put all the code in the other module(In your case "Admin" and "Canteen") in a class. That would work for you.

就像我在此示例中所做的那样:

Like I have done in this example:

模块_1:

import tkinter as tk


def test_func():
    from Module_2 import TestClass


root = tk.Tk()

b = tk.Button(root, text="Click", command=lambda: test_func())
b.pack()

root.mainloop()

Module_2:

class TestClass:
    import tkinter as tk
    root = tk.Toplevel()
    lbl = tk.Label(root, text="Test Label")
    lbl.pack()

这将为您服务
