Find string between two substrings [duplicate]


import res = 'asdf=5;iwantthis123jasd'result = re.search('asdf=5;(.*)123jasd', s)print(result.group(1))


s = "123123STRINGabcabc"def find_between( s, first, last ):    try:        start = s.index( first ) + len( first )        end = s.index( last, start )        return s[start:end]    except ValueError:        return ""def find_between_r( s, first, last ):    try:        start = s.rindex( first ) + len( first )        end = s.rindex( last, start )        return s[start:end]    except ValueError:        return ""print find_between( s, "123", "abc" )print find_between_r( s, "123", "abc" )

gives:

123STRINGSTRINGabc

I thought it should be noted - depending on what behavior you need, you can mix index and rindex calls or go with one of the above versions (it's equivalent of regex (.*) and (.*?) groups).


start = 'asdf=5;'end = '123jasd's = 'asdf=5;iwantthis123jasd'print s[s.find(start)+len(start):s.rfind(end)]

gives
