从程序的输出创建一个字典

问题描述

这是一个从 youtube 链接获取所有字幕的 Python 程序：

from pytube import YouTube
yt = YouTube('https://youtu.be/5MgBikgcWnY')
captions = yt.captions.all()
for caption in captions:
    print(caption)

上面程序的输出是：

<Caption lang="Arabic" code="ar">
<Caption lang="Chinese (China)" code="zh-CN">              
<Caption lang="English" code="en">
<Caption lang="English (auto-generated)" code="a.en">
<Caption lang="French" code="fr">
<Caption lang="German" code="de">
<Caption lang="Hungarian" code="hu">
<Caption lang="Italian" code="it">

但我只想从字典对中的上述输出中获取语言和代码。

{"Arabic" : "ar","Chinese" : "zh-CN","English" : "en","French : "fr","German" : "de","Hungarian" : "hu","Italian" : "it"} 

提前致谢。

解决方法

很简单

from pytube import YouTube

yt = YouTube('https://youtu.be/5MgBikgcWnY')
captions = yt.captions.all()
captions_dict = {}

for caption in captions:
    # Mapping the caption name to the caption code
    captions_dict[caption.name] = caption.code

如果你想要一个单线

captions_dict = {caption.name: caption.code for caption in captions}

输出
