python - Regex multiline replace -


so have this: 

z='===hello   there===,   how ===you===?'

and want be: 

z='<b>hello   there<\b>,   how <b>you<\b>?'

i tried doing this: 

z = re.sub(r"\={3}([^\$]+)\={3}", r"<b> \\1 </b>", z, re.m)

and works sort of got instead: 

z='<b>hello   there===,   how ===you<\b>?'

i'm still new believe it's ^ , $ makes match beginning , end of string. how change matches ones in middle? 

re.sub(r"\={3}([^\$]+?)\={3}", r"<b> \\1 </b>", z, re.m)

copy python docclick here:

*?, +?, ?? '*', '+', , '?' qualifiers greedy; match text possible. behaviour isn’t desired; if re <.*> matched against '<h1>title</h1>', match entire string, , not '<h1>'. adding '?' after qualifier makes perform match in non-greedy or minimal fashion; few characters possible matched. using .*? in previous expression match '<h1>'.
