【问题描述】：
我正在尝试做一个从 youtube 下载播放列表视频的程序，这就是程序：
from pytube import Playlist
from pytube import YouTube
playlist = Playlist('https://www.youtube.com/playlist?list=PLZ1u221jNfYGCxHU4RbChwG60X-_nq8HK')
print('Number of videos in playlist: %s' % len(playlist.video_urls))
for video_url in playlist.video_urls:
f = open (r'D:\Nueva carpeta (4)\lista_viejas.txt','a')
f.write("\n")
f.write(str(video_url))
f.close()
with open(r'D:\Nueva carpeta (4)\lista_viejas.txt', 'r') as file1:
with open(r'D:\Nueva carpeta (4)\lista_viejass.txt', 'r') as file2:
with open (r'D:\Nueva carpeta (4)\output.txt', "w") as out_file:
f2_lines = set(file2)
for line in file1:
if line not in f2_lines:
yt = YouTube(str(line))
video = yt.streams.first()
video.download(r'D:\Nueva carpeta (4)')
out_file.write(line)
f2_lines.add(line)
我不知道为什么我在这部分得到这个错误：
Exception has occurred: RegexMatchError
regex_search: could not find match for (?:v=|\/)([0-9A-Za-z_-]{11}).*
File "C:\Users\Andres\Desktop\Untitled-1.py", line 22, in <module>
yt = YouTube(str(line))
yt = YouTube(str(line))
video = yt.streams.first()
video.download(r'D:\Nueva carpeta (4)')
如果我将参数“line”更改为line_prove=input()，它可以工作。
