您如何获得所有视频的ID，标题和标签？

Question

我的目标是将ID，标题和标签附加到YouTube频道的所有视频的数组arr中。

这是我尝试过的

client = get_authenticated_service()
results1 = search_list_by_keyword(client,
  part='snippet',
  maxResults=50,
  channelId=someChannelId)  
for z in range(len(results1['items'])):  
  #print(results1['items'][z]['id'])     
  try:  
    id = results1['items'][z]['id']['videoId']
  except:
    continue;    
  results2 = videos_list_by_id(client,
      part='snippet,contentDetails,statistics',
      id=id)
  title = results2['items'][0]['snippet']['title']
  tags = results2['items'][0]['snippet']['tags']             
  print (title) 
  row = []
  row.append(id)
  row.append(title)
  row.append(tags)   
  if 'something' not in tags:
    arr.append(row)
nextPageToken = results1['nextPageToken']  
while 1==1: 
  try:
    print 'Continue at %s:' % (nextPageToken)   
    results1 = search_list_by_keyword(client,
      part='snippet',
      maxResults=50,
      channelId=someChannelId,
      pageToken=nextPageToken)
    nextPageToken = results1['nextPageToken']
    for z in range(len(results1['items'])): 
      id = results1['items'][z]['id']['videoId'] 
      results2 = videos_list_by_id(client,
          part='snippet,contentDetails,statistics',
          id=id)
      title = results2['items'][0]['snippet']['title']
      tags = results2['items'][0]['snippet']['tags']       
      print (title) 
      if 'Podcast' in tags:
        tags.remove('Podcast')
      row = []
      row.append(id)
      row.append(title)
      row.append(tags)   
      if 'something' not in tags:
        arr.append(row)
  except:
    break

和

def search_list_by_keyword(client, **kwargs):
  # See full sample for function
  kwargs = remove_empty_kwargs(**kwargs)

  response = client.search().list(
    **kwargs
  ).execute()

  return response

它一直工作到while 1==1，此后，print (title)打印的结果越来越少。标题的最终数量约为该频道公开视频总数的一半。
