我想删除python列表中第一个条目之前所有不必要的字符（粗体）。我正在尝试使用正则表达式来实现它，请检查我的代码？你知道吗

编辑：我想删除所有字符之前，包括字安全。你知道吗

def removePunctuation(text):
    text = re.sub(r"\x00+",'',text) 
    test = re.sub(r'.*a01', '',text)
    return text

Answer 1

OP:粗体文本没有规则。，假设损坏的文本以safe结尾：

import re

def removePunctuation(text):
    for elem in text:
        if elem.startswith('a01'):
            print(elem)
        else:
            elem = elem.rpartition('safe')[2]
            print(elem)

test_list = ['xian/gps_201610010000644016240301624032416162641013323634045015307 0ustar bigdata_safebigdata_safea01b8439e1e42ffcd286241b04d9b1b5,f11440a64a0f084fe346a398c62aa9ad,1475277482,108.92466,34.27657',
             'a01b8439e1e42ffcd286241b04d9b1b5,f11440a64a0f084fe346a398c62aa9ad,1475277488,108.92527,34.27658',
             'a01b8439e1e42ffcd286241b04d9b1b5,f11440a64a0f084fe346a398c62aa9ad,1475277506,108.9276,34.27659',
             'a01b8439e1e42ffcd286241b04d9b1b5,f11440a64a0f084fe346a398c62aa9ad,1475277476,108.92399,34.27655',
             'a01b8439e1e42ffcd286241b04d9b1b5,f11440a64a0f084fe346a398c62aa9ad,1475277515,108.9291,34.2766']



removePunctuation(test_list)

输出：
