Python的新手,我正在尝试使用BeautifulSoup来提升" ETH余额"来自etherscan.com网页的代码:
import bs4, requests
res = requests.get('https://etherscan.io/address/0x93673eeed88fda9423b8037374164383df54aec1')
res.raise_for_status()
soup = bs4.BeautifulSoup(res.text, 'html.parser')
ethBal = soup.find("td", text="ETH Balance").find_next("td").text
print('The ETH blance is '+ ethBal)
然而,我一直得到错误的内容如下:
Traceback (most recent call last):
File "/Users/tfountain/Desktop/python_work/c2.py", line 7, in <module>
ethBal = soup.find("td", text="ETH Balance").find_next("td").text
AttributeError: 'NoneType' object has no attribute 'find_next'
我哪里出错了,获得ETH余额的最佳途径是什么?

我使用正则表达式查找包含“&#39;以太”字样的td
。并且只是解析了那个标签。
代码:
import bs4, requests, re
res = requests.get('https://etherscan.io/address/0x93673eeed88fda9423b8037374164383df54aec1')
res.raise_for_status()
soup = bs4.BeautifulSoup(res.text, 'html.parser')
ethBal = soup.find('td', text=re.compile('Ether')).text
print('The ETH blance is '+ ethBal)
输出:
The ETH blance is
0 Ether

看一下页面源代码,HTML是:
<td>ETH Balance:
</td>
<td>
0 Ether
</td>
您正在搜索text='ETH Balance'
。但是文字是ETH Balance:
,最后有一个换行符。
所以,使用这个:
eth_bal = soup.find('td', text='ETH Balance:\n').find_next('td').text.strip()
print(eth_bal)
# prints '0 Ether'
