how add flags to python regex?

Question

I want to add a flag to my re.sub regex string. In PHP, I would just do this '\test is good\i'

I tried this in re.compile, but it does not have .sub method. I tried to use s.replace, but I cannot add the i flag to this as well

Answer 1

Compiled regex objects can be passed to re.sub(), so flags can still be passed in at compile time.

r = re.compile('test is good', re.IGNORECASE)
re.sub(r, 'yup', 'TEST IS GOOD')

Alternately, flags can be added with (?iLmsux) syntax:

re.sub('(?i)test is good', 'yup', 'TEST IS GOOD')
