Regular Expressions in python

Hi,

Can anyone tell me what mistake I am doing here in the code.?

names.py
import re

string = 'Perotto, Pier Giorgio'

names = re.match(r'''
    ([-\w ]*,)\s
    ([-\w ]+\s[-\w ]+)
''',string)

You are very close. There are two errors

  • in the first group, move the comma outside group
  • add missing re.X argument

Not an error, but the second group can be reduced. It reads one or more hyphen, word_char, or space; followed by a space; followed by one or more hyphen, word_char, or space.

Since the middle space and the second character set are also covered by the first character set, it can be reduced to ([-\w ]+).

As It is now, the first name would be required to have a space in it.

Post back if you need more help. Good luck!!!
