What difference did the space on the first name expression make? Why did it work with the space, but not without one?
import re
string = 'Perotto, Pier Giorgio'
names = re.match(r'([\w]*),\s([\w ]*)',string, re.I)
#names = re.match(r'([\w]*),\s([\w]*)',string, re.I) the code I had before I figured out the space

Post back if you have more questions. Good luck!!!

You need the space you discovered because the first name 'pier' is the first name and the only word in the string with an immediate trailing space.
This also passed for me:
import re
string = 'Perotto, Pier Giorgio'
names = re.match(r'([\w, ]*),\s([\w\s]*)',string, re.I)
So did this:
import re
string = 'Perotto, Pier Giorgio'
names = re.match(r'([\w,]*),\s([\w\s]*)',string, re.I)

I hope that helps.
Stay safe and happy coding!
