網站中的表格是動態加載的，因此您無法使用requests. 你必須使用selenium才能做到這一點。這是完整的代碼：
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)
輸出：
Symbol Quantity

我推薦一個非常好的工具，叫做 re，你可以從兩個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))

>>> 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)
