如何映射一个字符串内幕不包含数字的正则表达式报价

“记录一个”，“领域”：“随机ABC”，“申请B”：” random abc“，”filed c“：”123“
”record two“，”field a“：”random abc“，”filed b“：”random ab c“，”filed c“：”abc “

如何使用正则表达式从不包含任何数字的归档c中提取值？我试过这样的：

r"\"filed c\"\:\"([^\"\d]*)"

但它不工作。谢谢。

'filed'不是'field'。 –

说你有，

records = [ 
    '"record one","field a":"random a b c","filed b":"random a b c","filed c":"123"', 
    '"record two","field a":"random a b c","filed b":"random a b c","filed c":"abc"', 
    '"record ...","field a":"random a b c","filed b":"random a b c","filed c":"ab12c"', 
    '"record ...","field a":"random a b c","filed b":"random a b c","filed c":""', 
    '"record ...","field a":"random a b c","filed b":"random a b c","filed c":"12abc"', 
    '"record nth","field a":"random a b c","filed b":"random a b c","filed c":"Xyz"', 
]

什么做

import re 
rex = '"filed c":"([^\d]*)"' 
does_not_contain_any_number = [] 
for record in records: 
    q = re.compile(rex, re.DOTALL).findall(record) 
    if len(''.join(q)): 
     does_not_contain_any_number += q 


print(does_not_contain_any_number) 
#['abc', 'Xyz']
