Python Regular Expressions in Python Introduction to Regular Expressions Groups

Regex: why do we use the - in front of \w?

In this video and preceding videos, chris uses this set of caracters:

print(re.findall(r''' ([-\w ]+, \s[-\w ]+)\t ''', data, re.X))

I can't figure out why there is a - in front of the \w, since the names in the data file do not have a "-" in them.

Thanks!

Kathryn
