AttributeError:'HTMLParser'对象没有属性'unescape'

Question

我试图提取一些表格html，但它返回了一些错误，我不知道为什么

我真的需要一些帮助

代码：

from bs4 import BeautifulSoup
from io import BytesIO
import requests
import datetime
import re
import rows


# date = datetime.datetime.strptime("2013-1-25", '%Y-%m-%d').strftime('%m/%d/%y')
url = 'http://www1.caixa.gov.br/loterias/_arquivos/loterias/D_MEGA.HTM'

response = requests.get(url)
html = response.content


soup = BeautifulSoup(html, 'lxml')
tabela = soup.find("table")

for tag in tabela.find_all('table'):
    _ = tag.replaceWith('')


soup_tr = tabela.findAll("tr")
lista_tr = list(soup_tr)
lista_tr[0] = lista_tr[1]


s = "".join([str(l) for l in lista_tr])
s = "<table>" + s + "</table>"
s = re.sub("(<!--.*?-->)", "", s, flags=re.DOTALL)


table = rows.import_from_html(BytesIO(bytes(s, encoding='utf-8')))

输出错误如下：

  File "C:\Users\atendimentopcp300_01\Desktop\Antony\Blue Challenge\megasena.py", line 6, in <module>
    import rows
  File "C:\Users\atendimentopcp300_01\Desktop\Antony\Blue Challenge\venv\lib\site-packages\rows\__init__.py", line 22, in <module>
    import rows.plugins as plugins
  File "C:\Users\atendimentopcp300_01\Desktop\Antony\Blue Challenge\venv\lib\site-packages\rows\plugins\__init__.py", line 24, in <module>
    from . import plugin_html as html
  File "C:\Users\atendimentopcp300_01\Desktop\Antony\Blue Challenge\venv\lib\site-packages\rows\plugins\plugin_html.py", line 43, in <module>
    unescape = HTMLParser().unescape
AttributeError: 'HTMLParser' object has no attribute 'unescape'

这并不能真正解决您的错误，但是还有其他更简单的方法来解析来自web站点的表，而不是您已经开始使用的方法

以下是其中之一：

import pandas as pd
import requests

page = requests.get("http://www1.caixa.gov.br/loterias/_arquivos/loterias/D_MEGA.HTM")
df = pd.read_html(page.text, flavor="bs4")
print(df)
df = pd.concat(df).to_csv("your_magnificent_table.csv", index=False)

输出：

顺便说一句，用regular expressions来解析HTML是不受欢迎的，被认为是一个糟糕的选择Here's more on the topic
