[Tutor] New to Programming: TypeError: coercing to Unicode: need string or buffer, list found

[Saran Ahluwalia]

Danny,

You were spot on with that issue. I debugged this. Here are my two commits
for my homework: Starting with pyinotify
<https://github.com/ahlusar1989/WGProjects/blob/master/pyinotifyWGrun.py>
 and OS agnostic?
<https://github.com/ahlusar1989/WGProjects/commit/b8a2de25d45b1dc02b1dc189d2cfb71683fbdd9a?diff=unified#diff-0700a6bf321f99757963c11d7866aea4>
I
am still working on the latter - in regards to adding more customization
that fits the homework specifications.

Feel free to shoot me any critical feedback - when you can.

Cheers:

Saran
