tKinter条目不打印任何内容

Question

我正在使用python中的tktinter创建一个应用程序。我创建了一个名为“新任务”的按钮，该按钮调用了一个用户可以在其中输入链接的函数，然后创建了另一个按钮，在该按钮上调用了另一个函数，用户输入的链接被打印在控制台中，但是由于某种原因，它每次都不会打印任何内容。请帮助，这是代码

from tkinter import *
from tkinter.ttk import *
import tkinter as tk              
LARGE_FONT= ("Verdana", 12)


class SeaofBTCapp(tk.Tk):

    def __init__(self, *args, **kwargs):

        container.pack(side="top", fill="both", expand = True)
        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)

        self.frames = {}

        for F in (Task,LoginPage):

            frame = F(container, self)

            self.frames[F] = frame

            frame.grid(row=0, column = 0, sticky="nsew")

        RunningTask = tk.Label(self, text='Running Task').place(x=10,y=75,anchor=tk.NW)

        #canvas = Canvas(self, width=60, height=60)
        #canvas.place(x=10, y=30)

def taskcreator():
    global screen
    screen = Tk()
    thelink = StringVar()
    screen.geometry('720x640')
    Label(screen, text='Enter Shoe Link').place(x=10, y=20)
    linkentry = Entry(screen, textvariable=thelink)
    linkentry.place(x=10, y=40)
    you = Button(screen, text='End Task', command=lambda: assign(thelink))
    you.pack()
    screen.mainloop()

def assign(thelink):
    link = thelink.get()

    # print(llink.get())
    print(thelink.get())

app = SeaofBTCapp()
app.mainloop()

谢谢您的帮助！

更改assign(linkentry)和在您的功能上只分配print(link)
