我在使用get_text（）时获得unicode格式。如何在DataFrame中将Unicode更改为字符串？

整洁数据需要适当的文字格式..... 以下是我的代码......

import requests
from pattern import web
from bs4 import BeautifulSoup
from pandas import *
url = 'http://www.mouthshut.com/product-reviews/amazonin-reviews-925670774-srch'
    r = requests.get(url)
    bs = BeautifulSoup(r.text)
    mouthrev = []
    Title = []
    for revlist in  bs.find_all("li","reviewdetails openshare"):
        title = revlist.find_all('div','reviewtitle fl')
        title = [g.get_text(strip=True) for g in title]

        for parent in revlist.find_all("div", itemprop='description'):
            review = parent.find_all('p')
            review = [g.get_text(strip=True) for g in review]
            mouthrev.append(review)
            Title.append(title)


    mouth1 = DataFrame({'Title' : Series(Title),'Review' : Series(mouthrev)})
    mouth1.to_csv('D:\\Review.csv')

我收到了结果：

Answer 1

如果我理解你为什么不使用str（）

review = [str(g.get_text(strip=True)) for g in review]

这将起作用

Answer 2

这与Unicode无关。 [...]是列表的表示（repr）。您在每个单元格中都有一个列表，因为您正在获取多个p元素的文本：

title = [g.get_text(strip=True) for g in title]
review = [g.get_text(strip=True) for g in review]

如果你想从中形成一个单独的字符串，你可以将多个p文本连接在一起作为行，例如：

review = '\n'.join(g.get_text(strip=True) for g in review)

然后CSV格式化程序将有一个字符串而不是列表，因此它不必尝试通过repr将数据强制转换为字符串。
