Pytube and the new # channel urls - python-3.x

Question

I have been working on a python program for a little bit now that can take channel or video urls and convert them into a channel ID.
However my code doesn't seem to work with links that look like "http://youtube.com/#username"
if re.search ("/channel/", channelURL) or re.search ("#", channelURL) or re.search ("/user/", channelURL) or re.search ("/c/", channelURL):
# This code detects if the given URL is a channel. If the check comes back as True then it grabs the data using pytube.
c = Channel(channelURL)
channel_name = c.channel_name
channel_id = c.channel_id
channel_id_link = "http://youtube.com/channel/"+channel_id
print("Channel Name: "+channel_name)
print("Channel ID: "+channel_id)
print("Channel Link: "+channel_id_link)
You can see the full code here. https://github.com/flyinggoatman/YouTube-Link-Extractor/blob/master/QualityYouTube.py
What I expect, the code to be able pull the channel_name, channel_id and also the channel_id_link.
What happens?
The code runs but when I enter in a # youtube channel URL it returns the following

I understand I don't think the code will run with the current workings. However, can i somehow take the url and use the regex "#(.*)" to grab the username, and then use pytube to find a video made by that channel? I could then take the video URL and use that to get the information I need instead.

Note I fixed the issue by coding new lines of code inside "C:\Users[redacted]\AppData\Local\Programs\Python\Python310\lib\site-packages\pytube\extract.py"
https://github.com/pytube/pytube/pull/1444
I added the following lines of code
- :samp:`https://youtube.com/#{channel_name}/*
r"(?:(#$[%\w\d_-]+)(.*)?)"
to this file inside the github for PyTube
https://github.com/pytube/pytube/blob/master/pytube/extract.py
The changes look like this...
def channel_name(url: str) -> str:
"""Extract the ``channel_name`` or ``channel_id`` from a YouTube url.
This function supports the following patterns:
- :samp:`https://youtube.com/c/{channel_name}/*`
- :samp:`https://youtube.com/channel/{channel_id}/*
- :samp:`https://youtube.com/u/{channel_name}/*`
- :samp:`https://youtube.com/user/{channel_id}/*
- :samp:`https://youtube.com/#{channel_name}/*`
:param str url:
A YouTube url containing a channel name.
:rtype: str
:returns:
YouTube channel name.
"""
patterns = [
r"(?:\/(c)\/([%\d\w_\-]+)(\/.*)?)",
r"(?:\/(channel)\/([%\w\d_\-]+)(\/.*)?)",
r"(?:\/(u)\/([%\d\w_\-]+)(\/.*)?)",
r"(?:\/(user)\/([%\w\d_\-]+)(\/.*)?)",
r"(?:(#[%\w\d_-]+)(.*)?)"
]
for pattern in patterns:
regex = re.compile(pattern)
function_match = regex.search(url)
if function_match:
logger.debug("finished regex search, matched: %s", pattern)
uri_style = function_match.group(1)
uri_identifier = function_match.group(2)
return f'/{uri_style}/{uri_identifier}'
raise RegexMatchError(
caller="channel_name", pattern="patterns"
)
