Python正则表达式:用HTML链接替换字符串中的所有URL。巴布亚新几内亚。gif。jpg。jpeg

你可以用 re.sub

import re
def href(d, skip = ['.png', '.gif', '.jpg', '.jpeg']):
  return f'<a href="{d}">{d}</a>' if not re.findall('|'.join(skip), d) else d

s = """
La-la-la https://example.com/ https://example.com/
https://example.com/ la-la-la https://example.com/
la-la-la https://example.com/ la-la-la
"""
new_s = re.sub('https*://.*?(?=[\s$])', lambda x:href(x.group()), s)

输出:

La-la-la <a href="https://example.com/">https://example.com/</a> <a href="https://example.com/">https://example.com/</a> <a href="https://example.com/">https://example.com/</a> la-la-la <a href="https://example.com/">https://example.com/</a> la-la-la <a href="https://example.com/">https://example.com/</a> la-la-la

`badtags = ['.png', '.gif', 'jpg', 'jpeg']
 goodurls = ['https://', 'http://']
 for line in string:
     for word in line.strip().split():
         if(word[0:7] == 'https://' or word[0:6] == 'http://'):
             if(not word[-4:] in badtags):
                 // replace logic
`

这是一种相当简单的方法,您可能需要使用一个常规的for循环迭代来索引原始数组。
