I can't find the source of my Traceback Error

Here is the code:

line = re.search(r'''
    ^(?P<name>[-\w ]*,\s[-\w ]+)\t  # last and first names
    (?P<email>[-\w\d.+]+@[-\w\d.]+)\t  #  email address
    (?P<phone>)\(?\d{3}\)?-?\s?\d{3}-\d{4})?\t  #phone numbers
    (?P<job>[\w\s]+,\s[\w\s.]+)\t?  #job and company
    (?P<twitter>@[\w\d]+)?$  #twitter handle
''', data, re.X|re.M)

Here is the message I get
