res = requests.get(\'https://etherscan.io/token/tokenholderchart/0x86fa049857e0209aa7d9e616f7eb3b3b78ecfdb0?range=10\')
res.encoding=\'gbk\'
soup = BeautifulSoup(res.text,\'html.parser\')
table = soup.select(\'#ContentPlaceHolder1_resultrows table tr\')
myarr = []
for tr in table:
    td = tr.select(\'td\')
    if len(td) > 0:
        Rank = td[0].text;
        Address = td[1].text;
        Quantity = td[2].text;
        Percentage = td[3].text;
        myarr.append({"Rank": Rank, "Address": Address, "Quantity": Quantity, "Percentage": Percentage})
print(myarr)
