我想计算数据框中的段落数。然而，事实证明我的结果在列表中为零。有人知道如何修复它吗？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)
