Wolfram Alpha Python APIが動作しない

Question

私はMacOS Sierra 10.12.3でPython 3.6を使用しています。 wolframalphaをインストールし、私のアプリケーションIDが有効であることを確認しました（RESTfulを使用したURLリクエストで正常に動作します）。しかし、Wolframの独自のドキュメントからこの例を試してみると、このエラーが発生します。

During handling of the above exception, another exception occurred:

    raise URLError(err) 
urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:749)> 

任意のアイデア：

import wolframalpha 

client = wolframalpha.Client('xxxxxx-xxxxxxxxxxx') 

res = client.query('temperature in Washington, DC on October 3, 2012') 

は私にこれらのエラーを与えますか？もう何をすべきか分かりません。前もって感謝します。

Answer 1

ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed

は、import sslも行う必要があることを示します。
