我想修改下面的脚本,以便它从脚本生成的随机数量的句子中创建段落.换句话说,在添加换行符之前连接一个随机数(如1-5)的句子.

脚本工作正常,但输出是由换行符分隔的短句.我想把一些句子收集成段落.

关于最佳实践的任何想法？谢谢.

好吧,我拼凑了一个简单的“段落包装器”,它可以很好地将句子收集到段落中,但它与句子生成器的输出相混淆 – 我对第一个单词的重复性过高,例如,其他的问题.

但前提是声音;我只需要弄清楚为什么句子循环的功能受到段落循环的添加的影响.如果您能看到问题,请告知：

将以下句子中的句子= []添加到elif语句中.以机智;

        elif newword in stopsentence:
            print ("%s%s" % (" ".join(sentence),end=" ")
            sentence = [] # I have to be here to make the new sentence start as an empty list!!!
            sentencecount += 1 # increment the sentence counter

这是此脚本的最后一次迭代.感谢悲伤帮助整理出来.我希望其他人可以玩得开心,我知道我会的.
