构建Python的正则表达式

Question

\b(?:AN|AcntNumber) : (\w+)

上述正则表达式也会打印'AcntNumber'

AcntNumber : c422731c7c2a4f9cbe98fbfbf410265f 

但我只想打印c422731c7c2a4f9cbe98fbfbf410265f。有人可以帮帮我吗？

从:拆分字符串，您就拥有了帐号。

>>> string = "AcntNumber : c422731c7c2a4f9cbe98fbfbf410265f"
>>> frags = string.split(':')
>>> number = frags[1].strip()
>>> number
'c422731c7c2a4f9cbe98fbfbf410265f'

或者：

>>> import re
>>> string = "AcntNumber : c422731c7c2a4f9cbe98fbfbf410265f"
>>> e = "\b?:AN|AcntNumber : (\w+)"
>>> ext = re.findall(e, string)
>>> ext[0]
'c422731c7c2a4f9cbe98fbfbf410265f'
>>>
