I want Help for Google colab

[Woomer]

Hey I see you look very experienced in Google colab

I found an error using Google colab for some of my small projects
I didn't find any solution in any community like stack overflow,and other community

So I get you

The code is

import os
import google_auth_oauthlib.flow
import googleapiclient.discovery

scopes = ["https://www.googleapis.com/auth/youtube.readonly"]

def main():
os.environ["OAUTHLIB_INSECURE_TRANSPORT"] = "1"

api_service_name = "youtube"
api_version = "v3"
client_secrets_file = "/content/credentials.json"

# Get credentials and create an API client
flow = google_auth_oauthlib.flow.InstalledAppFlow.from_client_secrets_file(
    client_secrets_file, scopes,redirect_uri="http://localhost:8800/")

authorization_url, _ = flow.authorization_url()

print(f"Please go to this URL to authorize: {authorization_url}")
authorization_response = input("Paste the authorization code here: ")

flow.fetch_token(
    "https://accounts.google.com/o/oauth2/token",
    authorization_response=authorization_response
)

youtube = googleapiclient.discovery.build(
    api_service_name, api_version, credentials=flow.credentials)

request = youtube.channels().list(
    part="snippet,contentDetails,statistics",
    mine=True
)
response = request.execute()

print(response)

if name == "main":
main()

When opening the link and selecting my account after that it showing me
