【python 正则表达式】python正则表达式提取邮箱、网址、手机号、ip地址

要从文本中提取电子邮件、url、手机号、ip地址等，我们可以使用杀手锏正则表达式。下面是我封装的函数，方便以后拿来直接用。

# encoding: utf-8


import re

# 自定义获取文本电子邮件的函数
def get_findAll_emails(text):
    """
    :param text: 文本
    :return: 返回电子邮件列表
    """
    emails = re.findall(r"[a-z0-9\.\-+_]+@[a-z0-9\.\-+_]+\.[a-z]+", text)
    return emails



# 自定义获取文本手机号函数
def get_findAll_mobiles(text):
    """
    :param text: 文本
    :return: 返回手机号列表
    """
    mobiles = re.findall(r"1\d{10}", text)
    return mobiles


# 自定义获取文本url函数

def get_findAll_urls(text):
    """
    :param text: 文本
    :return: 返回url列表
    """
    urls=re.findall(r"(http[s]?://(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*,]|(?:%[0-9a-fA-F][0-9a-fA-F]))+)|([a-zA-Z]+.\w+\.+[a-zA-Z0-9\/_]+)",text)
    urls=list(sum(urls,()))
	urls=[x for x in urls if x!='']
    return urls



# 自定义获取获取ip地址函数

def get_findAll_ips(text):
    """
    :param text: 文本
    :return: 返回ip列表
    """
    ips = re.findall(r"\b(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\b", text)

    return ips



if __name__ == '__main__':
    
    content = "Please 42.121.252.58:443 contact 127.0.0.1  15988455173 us 18720071239 https://blog.csdn.net/u013421629/ at https://www.yiibai.com/ [email protected] for further information [email protected] You can  also give feedbacl at [email protected]"
    emails=get_findAll_emails(text=content)
    print emails
    moblies=get_findAll_mobiles(text=content)
    print moblies
    urls=get_findAll_urls(text=content)
    print urls
    ips=get_findAll_ips(text=content)
    print ips

运行结果：
