Regexp flags in Python

A possibly redundant flag

Report a typo

import re

string = '''I love dogs,
I love cats'''
result = re.findall('^I', string, re.MULTILINE)
print(result)

Is the re.MULTILINE flag necessary in the function above to match all I's in the string?

Select one option from the list

No, we need to use re.DOTALL to match a newline instead.

No, because re.findall will match all I's anyway.

Yes, because by default ^ matches only the beginning of the first string.

Yes, because the more flags the better.
