link = input("enter link of youtube vadio:")
yt = YouTube(link)
videos = yt.streams.filter(subtype='mp4').all()

i = 1
for stream in videos:
    print(str(i) + " " + str(stream))
    i += 1

stream_number = int(input("enter number:"))

video = videos[stream_number-1]
# vadio文件夹必须存在，否则报错
video.download("D:/vadio")
print("downloaded")
