A flag is just an int. From the re doc, you can see there is a ignorecase flag:
"
I
IGNORECASE
Perform case-insensitive matching; expressions like [A-Z] will match lowercase letters, too. This is not affected by the current locale.
"
Using the ignorecase flag:
>>> import re
>>> print re.I
2
>>> print re.IGNORECASE
2
>>> r = re.compile("hello", re.IGNORECASE)
>>> print r.pattern
'hello'
>>> match = r.search("heLLo")
>>> match.group()
'heLLo'As the doc says, you can combine several flags with the '|' operator:
r = re.compile("your_regexp", re.SOMEFLAG|re.SOMEOTHERFLAG)Xah Lee wrote:
Python re module has methods flags and pattern. How to use these exactly?
e.g. i tried
print patternObj.flags()
and the error is some "int object is not callable".
newpattern=re.compile(ur'\w+',patternObj.flags())
also bad.
similar error for patternObj.pattern(). (and i suppose the same for groupindex() )
thanks.
