以下のスクリプトを変更して、スクリプトによって生成されたランダムな数の文から段落を作成するようにします。つまり、改行を追加する前に、ランダムな数(1〜5など)の文を連結します。
スクリプトはそのままで問題なく動作しますが、出力は改行で区切られた短い文です。いくつかの文章を段落にまとめたいと思います。
ベストプラクティスに関するアイデアはありますか?ありがとう。

さて、私は単純な「段落ラッパー」をまとめました。これは、文を段落にまとめるのにうまく機能しますが、文ジェネレーターの出力を台無しにしました。たとえば、最初の単語が過度に繰り返されています。問題。
しかし、その前提は健全です。文ループの機能が段落ループの追加によって影響を受けた理由を理解する必要があります。あなたが問題を見ることができるかどうかアドバイスしてください:

以下の回答に従ってelif
ステートメントに追加されました。ウィットに;
elif newword in stopsentence:
print ("%s%s" % (" ".join(sentence), newword), end=" ")
sentence = [] # I have to be here to make the new sentence start as an empty list!!!
sentencecount += 1 # increment the sentence counter

これは、このスクリプトの最後の反復です。これを整理するのに助けてくれて悲しんでくれてありがとう。他の人がこれを楽しんでくれることを願っています、私はそうすることを知っています。;)
参考:小さなアーティファクトが1つあります。このスクリプトを使用する場合は、余分な段落の終わりのスペースをクリーンアップする必要があります。しかし、それ以外は、マルコフ連鎖テキスト生成の完璧な実装です。
