Python Tkinter异常回调

我还在做我的Tkinter小项目，这是一个简单的youtube视频下载程序 每次我尝试使用tkinter窗口时，它都会给我一个异常回调和值错误

Exception in Tkinter callback
Traceback (most recent call last):

ValueError: too many values to unpack (expected 2)

这是密码

import tkinter as tk
from pytube import YouTube

def downloadVid():
    global E1
    string =E1.get()
    yt = YouTube(str(string))
    videos = yt.get_videos()
    s=1
    for v in videos:
        print(str(s) + '.' + str(v))
        s +=1
    n=int(input("Enter your choice"))
    vid=videos[n-1]
    destination=str(input("Enter your destination"))
    vid.download(destination)
    print(yt.filename+"\n Ha been downloaded")
root=tk.Tk()

w=tk.Label(root,text="Youtube Downloader")
w.pack()


E1=tk.Entry(root,bd=5)
E1.pack(side=tk.TOP)


button=tk.Button(root,text="Download",fg="red",command=downloadVid   )
button.pack(side=tk.BOTTOM)

root.mainloop()

在cipher.py中编辑一行，如github链接所示，为我解决了这个问题

换句话说，错误消息存在一个问题，即self.transform\u计划中没有“.”。该错误表明在tk.Entry（）中输入的值的“.”多于预期值。请澄清最终出错时在tk.Entry（）中输入的内容。换句话说，错误消息存在一个问题，即在self.transform_计划中没有“.”。该错误表明在tk.Entry（）中输入的值比预期的“.”多。请澄清tk.Entry（）最终出错时输入的内容。
