My code is not complete but I need feedback on what’s missing or what needs to be corrected.
import re
string = 'Perotto, Pier Giorgio'
names=re.match("?P<last name>(P\w+)\W\s?P<first name>(P\w+)",string)
print(names.groups())

Treehouse Moderator 68,441 PointsYou are very close. Here are the items to correct:
- The named groups should be of the form
(?P<group_name>regex)
. As you have it, the opening paren is in the wrong place and there is an extra "P" in the pattern. - The group names can not have a space. This should be an underscore _
- The first_name group should accept a space in the name. Hint: you can use a character set: [ \w]
- To avoid using double backslashes
\\
, the string should be prefixed with an r to signify a "raw string" where the single backslash isn't interpreted as an escape. Otherwise, all single-backslashes would have to be coded as double-backslashes.
With these corrections, the code should pass.
Post back if you need more help. Good luck!!

Treehouse Moderator 68,441 PointsLeo Marco Corpuz, you’re getting closer! In your updated code:
names=re.match(r'(?P<last_name>(P\w+)\W\s<first_name>(P\w+)'),string)
Bullet points 2 & 4 were fixed, but not the point 1 & 3.
The \s you have between the groups is correct. There needs to be something additional in the pattern for the first_name
group to account for the space between the two first names. See the section on [] Used to indicate a set of characters
in the re docs.

18,975 PointsHere's my updated code. I don't understand the third correction. Isn't "\s" used for a space?
