Question

我尝试使用python提取表但是无法删除\ n尽管使用了replace，remove，rsplit，lsplit函数。请帮忙。

以下是我的代码。

from urllib.request import urlopen
from bs4 import BeautifulSoup
import requests
import pandas as pd

url = "https://shared.websol.barchart.com/quotes/quote.php?page=quote&sym=ng&x=13&y=8&domain=if&display_ice=1&enabled_ice_exchanges=&tz=0&ed=0"

res = requests.get(url)

soup = BeautifulSoup(res.text, 'lxml')

soup.prettify()

Header = soup.findAll('tr', limit=2)[1].findAll('th')

column_headers = [th.getText() for th in soup.findAll('tr', limit=2)[1].findAll('th')]

print(column_headers)

data_rows = soup.findAll('tr')[2:]

i = range(len(data_rows))

for td in data_rows:
    row = td.get_text()
    print(row)

我的代码输出如下。只复制了几行。

Answer 1

我将您的输出保存到res变量并调用res.replace("\n","")并且它有效。尝试在每一行上调用它。

Answer 2

也许这更接近你想要完成的事情：

from bs4 import BeautifulSoup
import requests

url = "https://shared.websol.barchart.com/quotes/quote.php?page=quote&sym=ng&x=13&y=8&domain=if&display_ice=1&enabled_ice_exchanges=&tz=0&ed=0"
res = requests.get(url)
soup = BeautifulSoup(res.text, 'lxml')

column_headers = [th.getText() for th in soup.findAll('tr', limit=2)[1].findAll('th')]
print(column_headers)

data_rows = soup.findAll('tr')[2:]
for td in data_rows:
    row = td.get_text().replace('\\n', '').strip()
    print(row)

从已删除的表中删除\ n
