#50731 — help on python regular expression named group

[Multipart message — attachments visible in raw view] — view raw

Dear All,

Here is my script :

#!/usr/bin/python
import re

# A string.
logs = "date=2012-11-28 time=21:14:59"

# Match with named groups.
m =
re.match("(?P<datetime>(date=(?P<date>[^\s]+))\s+(time=(?P<time>[^\s]+)))",
logs)

# print
print m.groupdict()

Output:
========

{'date': '2012-11-28', 'datetime': '*date=2012-11-28 time=21:14:59*',
'time': '21:14:59'}


Required output :
==================

{'date': '2012-11-28', 'datetime': '*2012-11-28 21:14:59*', 'time':
'21:14:59'}

need help to correct the below regex

(?P<datetime>(date=(?P<date>[^\s]+))\s+(time=(?P<time>[^\s]+)))"

so that It will have : 'datetime': '2012-11-28 21:14:59' instead of
'datetime': 'date=2012-11-28 time=21:14:59'

any help would be greatly appreciated

Thanks
Mohan L

Not sure, I'm correct. I took you precise string to
refresh my memory.

>>> import re
>>> tmp = 'date=\d{4}-\d{2}-\d{2}'
>>> DatePattern = '(?P<DATEPATTERN>' + tmp + ')'
>>> tmp = 'time=\d{2}:\d{2}:\d{2}'
>>> TimePattern = '(?P<TIMEPATTERN>' + tmp + ')'
>>> pattern = DatePattern + ' ' + TimePattern
>>> pattern
'(?P<DATEPATTERN>date=\\d{4}-\\d{2}-\\d{2}) (?P<TIMEPATTERN>time=\\d{2}:\\d{2}:\\d{2})'
>>> CompiledPattern = re.compile(pattern)
>>> s = 'date=2012-11-28 time=21:14:59'
>>> mo = CompiledPattern.search(s)
>>> print(mo)
<_sre.SRE_Match object at 0x02CD4188>
>>> print(mo.groups())
('date=2012-11-28', 'time=21:14:59')
>>> print(mo.groupdict())
{'DATEPATTERN': 'date=2012-11-28', 'TIMEPATTERN': 'time=21:14:59'}
>>> print(mo.group(1), mo.group('DATEPATTERN'))
date=2012-11-28 date=2012-11-28
>>> print(mo.group(2), mo.group('TIMEPATTERN'))
time=21:14:59 time=21:14:59
>>>

I'm glad to see you doing something else, but I don't think you
understood his problem. Note that his problem has not solution, which
a few seconds of Googling has confirmed to me.

Right.

I did not pay attention to "date", "time" *and* "datetime".
