我想修改下面的腳本，以便從隨機數的腳本生成的句子中創建段落。換句話說，在添加換行符之前，連接一個隨機數（如1-5個）的句子。如何從馬爾可夫鏈輸出創建段落？
該腳本原樣工作，但輸出是由換行符分隔的短句子。我想收集一些句子成段落。
有關最佳實踐的任何想法？謝謝。

好吧，我已經拼湊一個簡單的「段落的包裝，」效果很好的句子聚集成段落，但它的輸出搞砸句子生成器 - 例如，在第一個單詞的重複性問題中，我遇到了其他問題。
但前提是合理的;我只需要弄清楚爲什麼句子循環的功能受到了段落循環的影響。請告知，如果你能看到的問題：

sentencecount += 1 # increment the sentence counter
else:
sentence.append(newword)
w1, w2 = w2, newword
print (paragraphsep) # newline space
paragraphs = paragraphs + 1 # increment the paragraph counter
# EOF
編輯02：
新增sentence = []按照下面的答案爲elif聲明。以機智;
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

這是這個劇本的最後一次迭代。感謝在整理這個問題上的幫助而感到悲傷。我希望別人可以有一些樂趣，我知道我會的。 ;）
供參考：有一個小的神器 - 有一個額外的段落結束空間，如果您使用此腳本，您可能需要清理。但除此之外，馬爾可夫鏈文本生成的完美實現。

糟糕！是的，我一定是在某個時候抽出來的，忘記把它放回去。謝謝你的見解！這幾乎成功了。似乎句子循環爲每個句子重新使用相同的開始單詞。關於如何混合它爲句子生成選擇的第一個單詞的任何想法？ –
我添加了一個不需要外部循環的獨立解決方案。 – grieve
我目前沒有安裝python 3，所以你可能需要調整第二個解決方案的語法。 – grieve
