I keep getting an empty array, where is my error?

I've written this code out a few times now, and I feel like I am transcribing it exactly as he says to do it, but every time I am getting an empty array [] rather than the results he does. Where is my error? I can't seem to find it.

print(re.findall(r'''
^([-\w ]*,\s[-\w ]+)\t
([-\w\d.+]+@[-\w\d.]+)\t
(\(?\d{3}\)?-?\s?\d{3}-\d{4})?\t
([\w\s]+,\s[/w/s.]+)\t?
(@[\w\d]+)?$
''', data, re.X|re.M))

What data are you applying this to? Or even better, make a snapshot of your workspace and post the link to it here.

In the part of the regex that parses the "job" field, there are some slashes where there should be backslashes:

                 (?P<job>[\w\s]+,\s[/w/s.]+)\t?  # original
                 (?P<job>[\w\s]+,\s[\w\s.]+)\t?  # fixed
