Get the DateTime of all Videos from a YouTuber

I want to do a fun project and calculate when a YouTuber is most likely to upload their next YouTube video based on previous releases and their release dates.

So I calculate how long the YouTuber needs on average between each upload, and then calculated when he will upload their next YouTube video.

But first I need all Date / Times from for example the last 50 videos of that specific YouTuber.Currently I'm trying to do that with Python and the Google Cloud "YouTube Data API v3".

I found a few lines of code online:

import osimport googleapiclient.discoveryfrom googleapiclient.errors import HttpErrorfrom google.oauth2.credentials import Credentials# Replace 'YOUR_API_KEY' with your API key or provide the path to your credentials fileapi_key = 'YOUR_API_KEY'# Create the API clientyoutube = googleapiclient.discovery.build('youtube', 'v3', developerKey=api_key)def get_channel_subscriber_count(channel_id):    try:        response = youtube.channels().list(part='statistics', id=channel_id).execute()        channel = response['items'][0]        subscriber_count = channel['statistics']['subscriberCount']        print(f"Subscriber Count: {subscriber_count}")    except HttpError as e:        print(f"An error occurred: {e}")# Replace 'CHANNEL_ID' with the ID of the specific YouTube channelchannel_id = 'CHANNEL_ID'get_channel_subscriber_count(channel_id)

I replaced the API Key with mine, and changed the channel_id to the name of the YouTuber (youtube.com/@RemusNeo) so I replace it with "RemusNeo".However I always get the following error message:

Traceback (most recent call last): File"C:\Users\Baseult\PycharmProjects\pythonProject\main.py", line 23, inget_channel_subscriber_count(channel_id) File "C:\Users\Baseult\PycharmProjects\pythonProject\main.py", line 15, inget_channel_subscriber_countchannel = response['items'][0] KeyError: 'items'

If I use the same code and do it manually with each video using the following code, then it works fine:

def get_video_details(video_id):    try:        response = youtube.videos().list(part='snippet', id=video_id).execute()        video = response['items'][0]        title = video['snippet']['title']        release_date = video['snippet']['publishedAt']        print(f"Title: {title}")        print(f"Release Date: {release_date}")    except HttpError as e:        print(f"An error occurred: {e}")# Replace 'VIDEO_ID' with the ID of the specific YouTube videovideo_id = 'VIDEO_ID'get_video_details(video_id)

I tried a few other methods, for example get the Subscriber Count of that YouTuber but that also didn't work. So I guess the code is outdated to access a YouTubers channel?

Would be awesome if someone could help me, thanks a lot :)
