参数——q:冲突选项字符串(s): -q在YouTube数据API中。

I am trying to search the youtube videos using YouTube Data API in python code. I am getting Argument Error and not able to fix this issue. Already few similar issues are there. But there is no solution given to this issue so far. How can I achieve the result ? I tried to use the same code given in youtube data API's github. I am getting the above mentioned error in the following code.

我试图用python代码中的youtube数据API搜索youtube视频。我得到了参数错误，无法解决这个问题。几乎没有类似的问题存在。但到目前为止，还没有解决这个问题的办法。我怎样才能达到这个结果?我尝试使用youtube数据API github上给出的代码。我在下面的代码中得到了上面提到的错误。

it works for me, maybe this works for you too:

它对我有用，也许对你也有用:

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()
