I am trying to replace all matching occurrences with title cases using the following script. When there is a newline character between filter words (in this case 'ABC' and 'DEF') that line doesn't get replaced as intended.

How can I ignore the newline character in this case?

Edit: I don't want to strip all newline characters entirely from the string, but only strip those between the filter words.

Edit2: I edited the text and script to better reflect on the issue I am experiencing. If I include flags=re.DOTALL argument, it will give me:

  mmm    = "Hello Hello Hello Hello Hello HelloHello Hello Hello Hello",Bbb   = "Bbb",

whereas the output I want is (notice that bbb is not capitalized):

  mmm    = "Hello Hello Hello Hello Hello HelloHello Hello Hello Hello",bbb   = "bbb",

The following is the script I am using.

test_string = '''mmm    = "hello hello hello hello hello hellohello hello hello hello",bbb   = "bbb",
'''rex = r'(?<= mmm)(.*)(?=\")'def maketitle(match_obj):return match_obj.group(0).title()formatted = re.sub(rex, maketitle, test_string, flags=re.DOTALL)print(formatted)

Use the re.DOTALL flag:

formatted = re.sub(rex, maketitle, string, flags=re.DOTALL)
print(formatted)

According to the docs:

re.DOTALL
Make the '.' special character match any character at all, including a newline; without this flag, '.' will match anything except a newline.
