uj5u.com熱心網友回復：
發生什么了？
這里的主要問題table是嵌入在一個由iframe動態src生成的JavaScript
怎么修？
一種選擇是使用Selenium導航來渲染iframe并抓取table：
...
driver.get(url)
driver.switch_to.frame('tokentxnsiframe')
soupblockdetails = BeautifulSoup(driver.page_source, 'html.parser')
for row in soupblockdetails.select("tr:has(td)")[:3]:
print(f"{' '.join(row.stripped_strings)}\t{row.a.get('href').split('/')[-1]}")
...
例子
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from bs4 import BeautifulSoup
url = 'https://bscscan.com/token/0x0D0b63b32595957ae58D4dD60aa5409E79A5Aa96?a=0x81e0ef68e103ee65002d3cf766240ed1c070334d'
driver = webdriver.Chrome(ChromeDriverManager().install())
driver.maximize_window()
driver.get(url)
driver.switch_to.frame('tokentxnsiframe')
soupblockdetails = BeautifulSoup(driver.page_source, 'html.parser')
for row in soupblockdetails.select("tr:has(td)")[:3]:
print(f"{' '.join(row.stripped_strings)}\t{row.a.get('href').split('/')[-1]}")
