为什么会说,TypeError:期望一个字符缓冲区对象?
import urllib
import re
myfile = open("C:\Users\Teli\Desktop\pro.txt", "w")
page = urllib.urlopen("http://www.samair.ru/proxy/ip-address-01.htm").read()
a = re.findall('\d+\.\d+\.\d+\.\d+', page)
myfile.write(a)
myfile.close()
答案 0 :(得分:2)
re.findall()
返回匹配列表,而不是字符串。你必须从中获取字符串:
import urllib
import re
with open(r'C:\Users\Teli\Desktop\pro.txt', 'w') as handle:
page = urllib.urlopen('http://www.samair.ru/proxy/ip-address-01.htm').read()
addresses = re.findall(r'(\d+\.\d+\.\d+\.\d+)', page)
handle.write('\n'.join(addresses))
