Python3 YoutubeDL 即使使用安静选项也会显示输出

Question

假设我有一个脚本，如下所示

import youtube_dl

options = {
    "quiet": True,
    "skip_download": True,
    "forcetitle": True,
    "forceurl": True,
    "format": "bestaudio[ext=m4a]/best[ext=mp4]/best[ext=webm]/best"}

with youtube_dl.YoutubeDL(options) as ydl:
    metadata = ydl.extract_info(f"ytsearch1: Never gonna give you up Rick Astley")

    title = metadata["entries"][0]["title"]
    url = metadata["entries"][0]["formats"][0]["url"]
    watch_id = metadata["entries"][0]["display_id"]
    extension = metadata["entries"][0]["ext"]

print("\n")
print("Results")
print(f"title: {title}")
print(f"url: {url}")
# do other stuff

其输出显示如下

Rick Astley - Never Gonna Give You Up (Video)

通过将

"quiet": True

传递到

ydl.extract_info

，我想我可以抑制所有输出。虽然这确实抑制了大部分输出，但我不想显示任何输出。
如何抑制 ydl.extract_info 的

all

输出？

感谢您的帮助！

Answer 1

这是一个小临时方案，只需导入 os 并在最后放置一行，说明 os.sys(“cls”) 或 os.system(“cls”)
