Python追加添加相同的数据

我正试图从韩国网站上提取股票价格和市值数据.

这是我的代码:

import requests
from bs4 import BeautifulSoup

response = requests.get('http://finance.naver.com/sise/sise_market_sum.nhn?sosok=0&page=1')
html = response.text
soup = BeautifulSoup(html, 'html.parser')

table = soup.find('table', { 'class': 'type_2' })
data = []
for tr in table.find_all('tr'):
    tds = list(tr.find_all('td')) 

    for td in tds:
        if td.find('a'):
            company_name = td.find('a').text 
            price_now = tds[2].text
            market_cap = tds[5].text 
            data.append([company_name, price_now, market_cap])    


print(*data, sep = "\n")

这就是我得到的结果. (抱歉韩文字符)

[‘삼성전자’, ‘43,650’, ‘100’]

[”, ‘43,650’, ‘100’]

[‘SK하이닉스’, ‘69,800’, ‘5,000’]

[”, ‘69,800’, ‘5,000’]

结果中的第二行和第四行不应该存在.我只想要第一行和第三行.第二和第四行来自哪里,如何摆脱它们?

最佳答案 亲爱的朋友,我认为问题是你应该检查td.find(‘a’).文本是否有值!

所以我将你的代码改为此,它的工作原理!

import requests
from bs4 import BeautifulSoup

response = requests.get(
    'http://finance.naver.com/sise/sise_market_sum.nhn?sosok=0&page=1')
html = response.text
soup = BeautifulSoup(html, 'html.parser')

table = soup.find('table', {'class': 'type_2'})
data = []
for tr in table.find_all('tr'):
    tds = list(tr.find_all('td'))

    for td in tds:
        # where magic happends!
        if td.find('a') and td.find('a').text:
            company_name = td.find('a').text
            price_now = tds[2].text
            market_cap = tds[5].text
            data.append([company_name, price_now, market_cap])

print(*data, sep="\n")
