python re.search not working on multiline string

 You need to use the re.S flag, not re.M.

• re.M (re.MULTILINE) controls the behavior of ^ and $ (whether they match at the start/end of the entire string or of each line).
• re.S (re.DOTALL) controls the behavior of the . and is the option you need when you want to allow the dot to match newlines.
