単語 (優先) を入力した場合、その単語が含まれる文全体を削除するにはどうすればよいでしょうか。以前に使用した方法は面倒でした。sent_tokenize を使用してパラ (13000 語以上) を分割し、1000 語以上をチェックする必要があったため、ループを実行して各文の各単語をチェックしました。400以上の文章があるので、これには多くの時間がかかります。

代わりに、パラでこれらの 1000 語をチェックしたいと思います。単語が見つかったら、前のすべての単語をピリオドまで選択し、後のすべての単語をピリオドまで選択します。

text = 'whatever....'
sentences = text.split('.')
good_sentences = [e for e in sentences if 'my_word' not in e]

それはあなたが探しているものですか？
