Question

我不熟悉使用Python进行编码，并且正在使用YouTube数据API构建网络抓取工具。我查看了YouTube的代码示例，但无法实现它们。尽管它应该很容易复制和粘贴，但是Eclipse给了我错误，而且我不确定如何修复它们以进行编译。

以下内容检索了在YouTube上进行关键字搜索的热门视频：

#!/usr/bin/python

# This sample executes a search request for the specified search term.
# Sample usage:
#   python search.py --q=surfing --max-results=10
# NOTE: To use the sample, you must provide a developer key obtained
#       in the Google APIs Console. Search for "REPLACE_ME" in this code
#       to find the correct place to provide that key..

import argparse

from googleapiclient.discovery import build
from googleapiclient.errors import HttpError


# Set DEVELOPER_KEY to the API key value from the APIs & auth > Registered apps
# tab of
#   https://cloud.google.com/console
# Please ensure that you have enabled the YouTube Data API for your project.
DEVELOPER_KEY = 'REPLACE_ME'
YOUTUBE_API_SERVICE_NAME = 'youtube'
YOUTUBE_API_VERSION = 'v3'

def youtube_search(options):
  youtube = build(YOUTUBE_API_SERVICE_NAME, YOUTUBE_API_VERSION,
    developerKey=DEVELOPER_KEY)

  # Call the search.list method to retrieve results matching the specified
  # query term.
  search_response = youtube.search().list(
    q=options.q,
    part='id,snippet',
    maxResults=options.max_results
  ).execute()

  videos = []
  channels = []
  playlists = []

  # Add each result to the appropriate list, and then display the lists of
  # matching videos, channels, and playlists.
  for search_result in search_response.get('items', []):
    if search_result['id']['kind'] == 'youtube#video':
      videos.append('%s (%s)' % (search_result['snippet']['title'],
                                 search_result['id']['videoId']))
    elif search_result['id']['kind'] == 'youtube#channel':
      channels.append('%s (%s)' % (search_result['snippet']['title'],
                                   search_result['id']['channelId']))
    elif search_result['id']['kind'] == 'youtube#playlist':
      playlists.append('%s (%s)' % (search_result['snippet']['title'],
                                    search_result['id']['playlistId']))

  print 'Videos:\n', '\n'.join(videos), '\n' 

  #ERROR above: Encountered 
  "\'Videos:\\n\'" at line 60, column 9. Was expecting one of:     <NEWLINE> 
   ...     "(" ...     "[" ...

  print 'Channels:\n', '\n'.join(channels), '\n'
  print 'Playlists:\n', '\n'.join(playlists), '\n'


if __name__ == '__main__':
  parser = argparse.ArgumentParser()
  parser.add_argument('--q', help='Search term', default='Google')
  parser.add_argument('--max-results', help='Max results', default=25)
  args = parser.parse_args()

  try:
    youtube_search(args)
  except HttpError, e: 
  #Getting another ERROR here that 'e' is an undefined variable
    print 'An HTTP error %d occurred:\n%s' % (e.resp.status, e.content)

任何指向正确方向的问题对解决问题都将非常有帮助。非常感谢！
