Error running notebook due to Python 3.6 being required

[jayqi]

When trying to run the notebook using Python 3.5, I got an error on the import line:

from itssutils.itssdata import RawITSSData, ITSSMetrics

Traceback (most recent call last):

SyntaxError: invalid syntax

I believe it's because in this line you're using Python's f-strings, which is a new feature in Python 3.6 but not available in previous versions.

I don't think it is documented or enforced anywhere as a requirement.
