返回的類文件對象的結果是一個字節對象。你可以將其解碼成unicode字符串和使用Unicode正則表達式:
>>> re.findall('\d+\.\d+\.\d+\.\d+', page.decode('utf-8'))
['056.249.66.50', '100.44.124.8', '103.31.250.115', '105.236.180.243', '105.236.21.213', '108.171.162.172', '109.207.61.143', '109.207.61.197', '109.207.61.202', '109.226.199.129', '109.232.112.109', '109.236.220.98', '110.196.42.33', '110.74.197.141', '110.77.183.64', '110.77.199.111', '110.77.200.248', '110.77.219.154', '110.77.219.2', '110.77.221.208']
