python - 如何从数据框中计算每篇文章的段落？

Question

我想从数据框中计算段落。但是，事实证明我的结果在列表中变为零。有人知道如何解决吗？非常感谢。

这是我的代码:

def count_paragraphs(df):
    paragraph_count = []
    linecount = 0
    for i in df.text:
        if i in ('\n','\r\n'):
            if linecount == 0:
                paragraphcount = paragraphcount + 1
    return paragraph_count

count_paragraphs(df)

df.text

使用 Series.str.count :

def count_paragraphs(df):
    return df.text.str.count(r'\n\n').tolist()
count_paragraphs(df)
