目前,我正在尝试完成一个脚本,以将来自youtube播放列表的链接通过youtube_dl传递给我,以便能够将其中的音频流传输到我的树莓派上的播放器中,但是我不知道如何重复该过程,而是要进行更改自动更改变量,而无需更改数组上的每个数字,例如:
import os
import pafy
import youtube_dl as yt
from youtube_dl import YoutubeDL
links = ["http://www.youtube.com/watch?v=JaSfjAIcGpQ",

y = YoutubeDL({
'format': 'bestaudio',
})
url = links[0]
r = y.extract_info(url, download=False)
print(r['ext'])
print(r['url'])
我正在尝试更改“链接[0]”的部分 所以我可以重复此过程,但无需手动更改数字,而是在python中进行。我还是python的新手。
答案 0 :(得分:0)
据我了解,您想遍历列表。您可以使用for循环来实现它。
像这样:
for link in links:
url = link
r = y.extract_info(url, download=False)
答案 1 :(得分:0)
上面的答案似乎还可以,只是添加其他方式来做到这一点: 最短版本:
extracted_details_list = [y.extract_info(url, download=False) for url in links] # list comprehension
长版本,可能更容易获得for循环的流:
for i in range(len(links)):
url = links[i]
r = y.extract_info(url, download=False)
print(r['ext'])
print(r['url']
