regEx works in notepad++ but not in python

let's say we have this:

.................
=== Operation 'abcd::ddca:dsd' ended in 1.234s   /1.234s (100.00%) execution time
................

Using notepad++, I am able to identify this with:

^\=* Operation '([\d\D]*)' ended in (\d*.\d*)s\s*/(\d*.\d*)s \([\d\D]*\) execution time

I want the operation name and execution times to be grouped.

In python, trying this:

exp=re.compile(r"^\=* Operation \'([\d\D]*)\' ended in (\d*.\d*)s\s*/(\d*.\d*)s \([\d\D]*\) execution time")

provides nothing. I've tried \\( for escaping the literal paranthesis but it didn't work. I'm guessing I don't need to do that since I'm using r"[exp]" when building the object expression.

Any ideas on how to get the same result as in notepad++?

LE: tried only with:

exp=re.compile(r"^\=* Operation \'([\d\D]*)\'", flags=re.MULTILINE)

still doesn't find anything.

LE2:

later in the code I'm using groups=exp.match(INPUT) and I get the pairs with groups.group(n)

ANSWER: the problem was match. Using search fixed the problem

The regular expression mentioned in the question is working for me without any change. 

>>> s = """
... .................
... === Operation 'abcd::ddca:dsd' ended in 1.234s   /1.234s (100.00%) execution time
... ................
... """
>>> import re
>>> exp = re.compile(r"^\=* Operation \'([\d\D]*)\' ended in (\d*.\d*)s\s*/(\d*.\d*)s \([\d\D]*\) execution time", flags=re.M)
>>> re.search(exp, s)
<_sre.SRE_Match object at 0x1038766b8>
>>> re.findall(exp, s)
[('abcd::ddca:dsd', '1.234', '1.234')]

Two things to consider though:

  1. Use re.M in the flags argument
  2. User search or findall method to do the matching. Make sure you are not using re.match because it will match only the beginning of the string.

Try this - I am not a regex guru, but this worked for me.

>>> i
"=== Operation 'abcd::ddca:dsd' ended in 1.234s   /1.234s (100.00%) execution time"
>>> exp = re.compile(r'^={3} Operation (.*?) ended in (\d+\.\d+s)(?:.*?)$')
>>> re.findall(exp,i)
[("'abcd::ddca:dsd'", '1.234s')]

I noticed that you have double quotes at the end of the abcd::ddca:dsd

So :

exp=re.compile(r"^\=* Operation '([\d\D]*)\" ended in (\d*\.\d*)s\s*/(\d*\.\d*)s \([\d\D]*\) execution time", flags=re.MULTILINE)

You need to allow the ^ to match the start of a line, not just the start of the entire string:

exp=re.compile(r"^\=* Operation '([\d\D]*)' ended in (\d*\.\d*)s\s*/(\d*\.\d*)s \([\d\D]*\) execution time", flags=re.MULTILINE)
