PyTube: PrivateVideo exception not working

问题

I wrote a code that will print all videos' name on the playlist. The problem is when it tries to print the name of the video that is private. I wrote an exception from Github that the owner wrote but it still doesn't work. It should skip this one video and go to another one but it doesn't and the program crashes. Here is my code:

import pytube
from pytube.exceptions import VideoPrivate

pl = pytube.Playlist("https://www.youtube.com/playlist?list=PLB1PGaMZkETOixDfsnKIOkfJS_cToCHSt")


for video in pl.videos:
    try:
        print(video.title)
    except VideoPrivate:
        continue

Error output:

python playlist.py
One Direction - Steal My Girl
One Direction - Drag Me Down (Official Video)
One Direction - Story of My Life
One Direction - Night Changes
One Direction - Perfect (Official Video)

    raise VideoPrivate(video_id=self.video_id)
pytube.exceptions.VideoPrivate: 8fGmghrkLco is a private video

回答1:

The exception is generated outside of the try/catch. It is actually being raised when the next item of pl.videos is yield.

@property
def videos(self) -> Iterable[YouTube]:
    """Yields YouTube objects of videos in this playlist

    :Yields: YouTube
    """
    yield from (YouTube(url) for url in self.video_urls)

Instead of calling videos, you may use video_urls

for video in pl.video_urls:
    try:
        print(YouTube(video).title)
    except VideoUnavailable:
        continue

Here we are using VideoUnavailable which is the baseClass for VideoPrivate

You will need the following imports:

import pytube
from pytube.exceptions import VideoUnavailable
from pytube import YouTube

Output:

One Direction - Steal My Girl
One Direction - Drag Me Down (Official Video)
One Direction - Story of My Life
One Direction - Night Changes
One Direction - Perfect (Official Video)
One Direction - You & I
