ArgumentError：引数--q：競合するオプション文字列：YouTube Data APIの--q

Question

YouTube Data APIを使用してYouTube動画をPythonコードで検索しようとしています。私は引数エラーを取得しており、この問題を解決できません。すでに類似の問題はほとんどありません。しかし、これまでのところ、この問題には解決策はありません。どうすれば結果を得ることができますか？私はyoutubeデータAPIのgithubで与えられた同じコードを使用しようとしました。上記のエラーが次のコードで発生しています。

from apiclient.discovery import build 
from apiclient.errors import HttpError 
from oauth2client.tools import argparser 


# 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 = "API KEY" # added perfectly 
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" 
    print "Channels:\n", "\n".join(channels), "\n" 
    print "Playlists:\n", "\n".join(playlists), "\n" 


if __name__ == "__main__": 
    argparser.add_argument("--q", help="Search term", default="funny videos") 
    argparser.add_argument("--max-results", help="Max results", default=25) 
    args = argparser.parse_args() 


    try: 
    youtube_search(args) 
    except HttpError, e: 
    print "An HTTP error %d occurred:\n%s" % (e.resp.status, e.content)

で、多分これはあまりにもあなたのために働く：

import argparse 
if __name__ == "__main__": 
    argparser = argparse.ArgumentParser(conflict_handler='resolve') 
    argparser.add_argument("--q", help="Search term", default="funny videos") 
    argparser.add_argument("--max-results", help="Max results", default=25) 
    args = argparser.parse_args()
