python中需要的正则表达式模式

Question

level=debug    msg="finishing determing prediction threshold" origin=placementadvice.ml version=Staging rid=01g40fv1vh9gpj0dkzaph6b31h tag=prediction_threshold_computation formation=VF duration=0.10032415390014648 time=2022-07-11T22:08:03.971697 

我可以得到正则表达式模式来让这些脱离上面的行吗

msg="finishing d"  formation=VF  duration=0.10032415390014648 

并进入数据框

Answer 1

您可以使用shlex而不是正则表达式：

import shlex

data = 'level=debug    msg="finishing determing prediction threshold" origin=placementadvice.ml version=Staging rid=01g40fv1vh9gpj0dkzaph6b31h tag=prediction_threshold_computation formation=VF duration=0.10032415390014648 time=2022-07-11T22:08:03.971697'

output_dict = dict(i.split('=') for i in shlex.split(data))

结果：

{'level': 'debug',
 'msg': 'finishing determing prediction threshold',
 'origin': 'placementadvice.ml',
 'version': 'Staging',
 'rid': '01g40fv1vh9gpj0dkzaph6b31h',
 'tag': 'prediction_threshold_computation',
 'formation': 'VF',
 'duration': '0.10032415390014648',
 'time': '2022-07-11T22:08:03.971697'}
