Answer 1

网站中的表格是动态加载的，因此您无法使用requests. 你必须使用selenium才能做到这一点。这是完整的代码：

from bs4 import BeautifulSoup

from selenium import webdriver

import time

import pandas as pd

url = 'https://bscscan.com/tokenholdings?a=0x00a2c3d755c21bc837a3ca9a32279275eae9e3d6'

driver = webdriver.Chrome()

driver.get(url)

time.sleep(5)

html = driver.page_source

driver.close()

soup = BeautifulSoup(html,'html5lib')

tbody = soup.find('tbody', id = "tb1")

tr_tags = tbody.find_all('tr')

symbols = []

quantities = []

for tr in tr_tags:

    td_tags = tr.find_all('td')

    symbols.append(td_tags[2].text)

    quantities.append(td_tags[3].text)

df = pd.DataFrame((symbols,quantities))

df = df.T

df.columns = ['Symbol','Quantity']

print(df)

输出：

  Symbol      Quantity

0    BNB   17.98420742

1   Cake   19.76899295

2    ANY             1

3   FREE         1,502

4    LFI  326.87340092

5    LFI  326.87340092

我推荐一个非常好的工具，叫做 re，你可以从两个子字符串中搜索特定的字符串，例如

import re

s = ''<td>THERE IS TEXT I WANT TO GET</td>"

result = re.search('<td>(.*)</td>', s)

print(result.group(1))

Answer 3

>>> html="<td>THERE IS TEXT I WANT TO GET</td>\n<td>THERE IS TEXT I WANT TO GET</td>\n<td>THERE IS TEXT I WANT TO GET</td>\n<td>THERE IS TEXT I WANT TO GET</td>"

>>> soup = BeautifulSoup(html)

>>> for td in soup.find_all('td'): print(td.text)
