I’m working on writing a parser to extract information from the output given below

Actually i need to get all the three texts which are inbetween ‘–‘. so i wrote a regular expression as below

import re
def parse_ib_write_bw(mystr):
    output = dict()
    # match = re.search('--+n(n|.)*?--+', mystr, re.I)
    match = re.search('--+n(.*)--+(.*)--+(.*)--+', mystr, re.DOTALL)

    if match:
        print(match.groups(1))
        print(match.groups(2))
        print(match.groups(3))

parse_ib_write_bw(my_str)

My understanding is:

--+n(.*)--+    -->  This would give the output of the first block  until second  '---' is found

(.*)--+ --> would give the second block until the third '--' is found 

(.*)--+ --> would give the third block until the final'--' is found 

but actually i get the entire output. kindly help me to understand where i;m going wrong with my understanding.
