[BUG] RegexMatchError get_throttling_function_name: could not find match for multiple

See original GitHub issue

Hello, I have problem with streams of YouTube wideo. I have tried everything I found on the net! I will be grateful for help!

My code:

from pytube import YouTube
yt = YouTube("https://www.youtube.com/watch?v=JLXBvVh8-2A")
yt.streams

My fucking error:

This fix by eroc1234 resolved it for me.

As noted by gangmax in the responses to that post, function_patterns is defined on line 264 of cipher.py The actual expressions to modify are on lines 272~273
