如何映射一個字符串內幕不包含數字的正則表達式報價

「記錄一個」，「領域」：「隨機ABC」，「申請B」：」 random abc「，」filed c「：」123「
」record two「，」field a「：」random abc「，」filed b「：」random ab c「，」filed c「：」abc 「

如何使用正則表達式從不包含任何數字的歸檔c中提取值？我試過這樣的：

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

但它不工作。謝謝。

'filed'不是'field'。 –

說你有，

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"', 
]

什麼做

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']
