Python：将电子邮件地址转换为HTML链接

Question

我正在寻找一种独立的Python函数，它将接收一个字符串并返回一个字符串，并将电子邮件地址转换为链接。

例子：

>>>s = 'blah blah blah [email protected] blah blah blah' 
>>>link(s) 
'blah blah blah <a href="mailto:[email protected]">[email protected]</a> blah blah blah' 

Answer 1

像这样的事情？

import re 
import xml.sax.saxutils 

def anchor_from_email_address_match(match): 
    address = match.group(0) 
    return "<a href=%s>%s</a>" % (
     xml.sax.saxutils.quoteattr("mailto:" + address), 
     xml.sax.saxutils.escape(address)) 

def replace_email_addresses_with_anchors(text): 
    return re.sub("\[email protected](?:\w|\.)+", anchor_from_email_address_match, text) 

print replace_email_addresses_with_anchors(
    "An address: [email protected], and another: [email protected]") 

Answer 2

def link(s): 
    return '<a href="mailto:{0}">{0}</a>'.format(s) 

Answer 3

>>> def convert_emails(s): 
...  words = [ word if '@' not in word else '<a href="mailto:{0}">{0}</a>'.format(word) for word in s.split(" ") ] 
...  return " ".join(words) 
... 
>>> s = 'blah blah blah [email protected] blah blah blah' 
>>> convert_emails(s) 
'blah blah blah <a href="mailto:[email protected]">[email protected]</a> blah blah blah' 
>>> 

不是超级强大的，但适用于非常基本的情况。
