Is there a way how can I improve my script to stop returning me data from the same channel? For example, I want my code to skip parsing video data from channels that were actually scraped yet and get me only one data result per one channel, not more.

youtube = build('youtube','v3',developerKey = api_key)

print(type(youtube))
pp = PrettyPrinter()
nextPageToken = ''

for x in range(1):
#while True:
    request = youtube.search().list(
        q='I stand with Ukraine',
        part='id,snippet',
        maxResults=5,
        order="viewCount",
        pageToken=nextPageToken,
        type='video')
    
    print(type(request))
    res = request.execute()
    pp.pprint(res) 
    
    if 'nextPageToken' in res:
        nextPageToken = res['nextPageToken']

To filter items to consider channels only once, just keep track of considered channels with a Python set and reconstruct items by filtering with this set.

To do so add before your loops:

channelIds = set()

And before the nextPageToken management, add:

    items = []
    for item in res['items']:
        channelId = item['snippet']['channelId']
        if not channelId in channelIds:
            channelIds.add(channelId)
            items  = [item]

    res['items'] = items
