Unsolvable Peyon Regex register in 2.6

Question

I have the following code that works in Python 2.7:

entry_regex = '(' + search_string + ')'
entry_split = re.split(entry_regex, row, 1, re.IGNORECASE)

I need to get it to work in Python 2.6, and also in Python 2.7 and 2.6 re.split does not accept the flag (re.IGNORECASE) as the fourth parameter. Any help? Thanks

Answer 1

You can simply add (? I) to the regular expression to make case insensitive:

>>> import re
>>> reg = "(foo)(?i)"
>>> re.split(reg, "fOO1foo2FOO3")
['', 'fOO', '1', 'foo', '2', 'FOO', '3']

Answer 2

Create re.RegexObjectwith re.compile(), and then call it split().

Example:

>>> re.compile('XYZ', re.IGNORECASE).split('fooxyzbar')
['foo', 'bar']

Answer 3

Oh, found it myself, I can compile it into a Regex object:

entry_regex = re.compile('(' + search_string + ')', re.IGNORECASE)
entry_split = entry_regex.split(row, 1)
