标签: python regex parsing ip

我正在尝试下载您可以找到here txt 文件。下载文件不是问题:

    testfile = urllib.URLopener()
    testfile.retrieve(_proxy_list_download_, "proxies.txt")

但问题是,当它被下载时,它表现得很奇怪。当我在任何 txt 编辑器中打开它时,我可以看到内容和 IP 地址,但是当我尝试将内容打印到控制台时,它会打印出来:

212.3.183.210:8080; 0; 0; anonymous proxy; Italy; ; a;  in); an Jose); ree download proxy IP

当我尝试从那里获取 IP 地址时,输出中没有地址。

with open('proxies.txt') as f:
            content = f.read()
            ip = re.findall( r"^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$", content )

我已经尝试了另一个正则表达式

r'([0-9]+)(?:\.[0-9]+){3}' 

正则表达式仅返回 3位数字。

您是否知道如何解析这些IP?

编辑:这是文本编辑器中的复制+粘贴文本,但在编辑器中,所有内容都在一行中:

您需要移除锚点,因为一条线路不会只包含一个IP地址。

ip = re.findall( r"\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b", content )

第二个正则表达式

r'([0-9]+)(?:\.[0-9]+){3}' 

必须返回三位数,因为只捕获了前三位数,re.findall方法会先返回捕获,如果有的话。如果没有捕获,则只返回匹配。通过将捕获组转换为非捕获组将为您提供所需的输出。

r'\b[0-9]+(?:\.[0-9]+){3}\b'
