I programmed a python program to download videos from YouTube

After I put the link and start the download I get the following error:

Exception in Tkinter callback

Traceback (most recent call last):

AttributeError: 'NoneType' object has no attribute 'span'

I can't tell exactly what the problem is!! Although the code was written in an orderly fashion! And everything is working properly!

I attach the following code for you:

Problem solved

Turns out when I entered the pytube library code in github I found all the comments confirming that the problem is from the same library but the library has been updated Now I updated the library and the program really worked without problems Write :

pip install --upgrade pytube
