Uploads to get multiple Video IDs, but the they don't return all data [items]

Newbie coder here, wanting to code for research purposes. I used Jupyter, Python 3

playlist_id = 'UUYk4LJI0Pr6RBDWowMm-KUw'

and then

def get_video_ids (youtube, playlist_id):    request = youtube.playlistItems().list(                part='contentDetails',                playlistId = playlist_id,                maxResults = 50)    response = request.execute()    video_ids = []    for i in range (len(response['items'])):        video_ids.append(response['items'][i]['contentDetails']['videoId'])    next_page_token = response.get('nextPageToken')    more_pages = True    while more_pages:        if next_page_token is None:            more_pages = False        else:                request = youtube.playlistItems().list(                            part='contentDetails',                            playlistId = playlist_id,                            maxResults = 50,                            pageToken = next_page_token)                response = request.execute()                for i in range (len(response['items'])):                    video_ids.append(response['items'][i]['contentDetails']['videoId'])                next_page_token = response.get('nextPageToken')    return video_ids

to get a long list of video ids

video_ids = get_video_ids (youtube, playlist_id)def get_video_details (youtube, video_ids):    all_video_stats = []    for i in range(0, len(video_ids), 50):        request = youtube.videos().list(                part='snippet,statistics',                id=','.join(video_ids[i:i+50]))        response = request.execute()    for video in response ['items']:        video_stats = dict(                        Title = video['snippet']['title'],                        Publish_date = video['snippet']['publishedAt'],                        View_Count = video['statistics']['viewCount']                        #Comment_Count = video['statistics']['commentCount']                            )        all_video_stats.append(video_stats)    return all_video_stats

when i tried to use get_video_details (youtube, video_ids)

It only shows 24 data, instead of all hundreds of videos in it.Help?

Was expecting to get hundreds of data with the use of len() function.
