I have python application with pytube and tkinter

Question

i made an application, where you can download a youtube video and choose the location of download. The problem is, it only work sometimes.

This is the error it is giving in console: Exception in Tkinter callback Traceback (most recent call last): File "C:UsersUserAppDataLocalProgramsPythonPython39libtkinter__init__.py", line 1885, in __call__ return self.func(*args) File "C:PythonVideoDownloaderVideoDownloader.py", line 39, in downloadVideo ytbvideo=YouTube(ytbLink).streams.filter(progressive=True, file_extension='mp4').order_by('resolution').desc().first() File "C:UsersUserAppDataLocalProgramsPythonPython39libsite-packagespytube__main__.py", line 91, in __init__ self.prefetch() File "C:UsersUserAppDataLocalProgramsPythonPython39libsite-packagespytube__main__.py", line 183, in prefetch self.js_url = extract.js_url(self.watch_html) File "C:UsersUserAppDataLocalProgramsPythonPython39libsite-packagespytubeextract.py", line 143, in js_url base_js = get_ytplayer_config(html)["assets"]["js"] KeyError: 'assets'

And this is my code:

import os
from tkinter import *
from tkinter import filedialog
import tkinter as tk



root= Tk()
root.geometry('600x400')
root.title('Youtube Video Downloader')
root.configure(bg='gray')



Label_1=Label(root,text="Youtube video downloader", font=("bold",20), bg='gray')
Label_1.place(x=150,y=10)

Label_2=Label(root, text="Paste the link here", font=(10), bg='gray')
Label_2.place(x=240, y=75)



mylink=StringVar()

pastelink=Entry(root, width=60, textvariable=mylink)
pastelink.place(x=140, y=100)



def chooseDir():
    global path
    path = filedialog.askdirectory(title="Choose a download directory")
    videoLoc = path
    tk.Label(root, text=path, bg='gray').place(x=240,y=300)

def downloadVideo():
    ytbLink=str(mylink.get())
    ytbvideo=YouTube(ytbLink).streams.filter(progressive=True, file_extension='mp4').order_by('resolution').desc().first()
    ytbvideo.download(videoLoc)


    
def quitApp():
    root.destroy()
    



   

Button(root,text="Download video", width=20, bg='black',fg="white", command=downloadVideo).place(x=240, y=130)
Button(root,text="Choose location", width=20, bg='black',fg="white", command=chooseDir).place(x=240, y=160)
Label_3=Label(root, text="Curent location: ", font=("bold"), bg='gray')
Label_3.place(x=250, y=245)

Label_3=Label(root, text="by yakubiq", font=("bold"), bg='gray')
Label_3.place(x=0, y=375)

Button(root,text="Quit", width=20, bg='black', fg='white', command=quitApp).place(x=445, y=370)



root.mainloop()

Im trying to fix it on my own, but still, im beginner and I started few days ago. In console, there is line 183, but i dont know, what does it mean

This issue is fixed on the newer version of pytube, just try to say pip uninstall pytube and then pip install pytube and then re-run your code again.

And as far as your tkinter code is concerned, you are assigning global to the wrong variable.

def chooseDir():
    global videoLoc #correct globalization
    path = filedialog.askdirectory(title="Choose a download directory")
    videoLoc = path
    tk.Label(root, text=path, bg='gray').place(x=240,y=300)

def downloadVideo():
    ytbLink = mylink.get() #no need to use str() as it is string by default 
    ytbvideo = YouTube(ytbLink).streams.filter(progressive=True, file_extension='mp4').order_by('resolution').desc().first()
    ytbvideo.download(videoLoc)

With these changes it should work, but keep in mind, in the example you gave, your not importing pytube, so it has to be like from pytube import YouTube. Though i would also suggest you use threading.

Answer 2

you forgot to import pytube

from pytube import Youtube

and the ytbvideo.download(videoLoc)

videoLoc is not defined
