re.match always gives at most one match, and that match has to start at the
beginning of the string:
>>> import re
>>> r = re.compile("foo", re.I)
>>> help(r.match)
Help on built-in function match:
match(...)
match(string[, pos[, endpos]]) --> match object or None.
Matches zero or more characters at the beginning of the string
>>> r.match("bar foobar")
>>>
Use re.findall() if you need all matches
>>> r.findall("foo FOObar")
['foo', 'FOO']
or re.finditer() if you need other information than just the matching
string:
>>> [m.start() for m in r.finditer("foo FOObar")]
[0, 4]
