Skipping the second and fourth lines brings the same results. Why would we use them? @Keneth Love

Treehouse Guest TeacherHmm, OK. That's totally possible! But why have those lines? Well, partly for explicitness (especially line 3) and partly for clean data (line 5).
If, somehow, I had a string like hello-there,what-is-happening, I wouldn't necessarily want it to match. The regex would prevent that because there's no whitespace after the comma. Also, if a line does end with a tab or newline, I don't want that tab or newline to be included in my results because they're not useful characters.

Treehouse Guest TeacherI'm not sure exactly what you mean by "second and fourth lines". Can you show me an example?
Daniel Petrov
3,495 PointsSorry my bad, it is actually 3 and 5. I am getting the same result with and without these two lines.
print(re.findall(re'''
\b[-\w]+,
\s <---
[-\w ]+
[^\t\n] <---
''', data, re.X))

229,732 PointsIt doesn't look like your tag for Kenneth Love was correctly converted into a link. This one should work.
And I don't know which "lines" you are referring to, but perhaps he will.
