如何使用Python打印播放列表中的所有视频名称？

Question

我想制作一个程序，打印播放列表中的所有视频名称，但第10行出现“'str'对象不可调用”错误。我怎样才能修好它，谢谢

from pytube import YouTube
from pytube import Playlist

p = Playlist("https://www.youtube.com/watch?v=p6IIWuwdNIc&list=PL3-sRm8xAzY-556lOpSGH6wVzyofoGpzU")
for url in p.video_urls[:10]:
    videourl = url

yt = YouTube(videourl)  
videonames = yt.title()

print(videonames)

Answer 1

使用title而不是title()：

from pytube import YouTube
from pytube import Playlist

playlist = Playlist("https://www.youtube.com/watch?v=p6IIWuwdNIc&list=PL3-sRm8xAzY-556lOpSGH6wVzyofoGpzU")

# Print first 10 video names in playlist
for url in playlist.video_urls[:10]:
    yt = YouTube(url)
    video_name = yt.title
    print(video_name)

输出：
