解压缩程序时删除\ n

Question

我为twitter上的粉丝数量做了一个正则表达式，我必须提取它

    # Create a regex for number of followers
    (
    (\s|-)          # first separator
    \d\d            # first 2 digits
    ,               # separator
    \d\d\d          # hundred thousands
    ,               # separator
    \d\d\d          # hundreds
    )
    ''', re.VERBOSE)

从此文本中提取用户名/关注者

extractedFollowers = followersRegex.findall(text)

   allFollowers = []
     for followerCount in extractedFollowers:
     allFollowers.append(followerCount[0])

但每当我运行它时，会出现：

['\n90,280,191', '\n84,239,451', '\n79,215,375', '\n75,925,596', '\n62,869,696']

如何删除\ n？

Answer 1

>>> lst = ['\n90,280,191', '\n84,239,451', '\n79,215,375', '\n75,925,596', '\n62,869,696']
>>> [i.replace('\n', '') for i in lst]
# ['90,280,191', '84,239,451', '79,215,375', '75,925,596', '62,869,696']

如果您提供有关正在应用正则表达式的原始字符串的更多信息，也许我可以帮助使用正则表达式部分。

Answer 2

您可以使用replace或lstrip。

>>>lst = ['\n90,280,191', '\n84,239,451', '\n79,215,375', '\n75,925,596', '\n62,869,696']
>>>[i.lstrip('\n') for i in lst]
['90,280,191', '84,239,451', '79,215,375', '75,925,596', '62,869,696']
