[Tutor] Finding Matplotlib somewhere ADDING ADDITIONAL INFORMATION

[Adam Eyring]

I tried
import matplotlib.dates
on my Win10 installation of Python 3.7.6 and it worked, though I don't have
a use for .dates. I normally use
import matplotlib.pyplot as plt
for my projects. I wonder if you should uninstall Python 2 and do a clean
re-install of Python 3 to see if that makes a difference. By looking at the
errors that come up when running bioyear.py, you can make adjustments to
work in Python 3, but I would expect it to be backwards compatible (I'm not
an expert on that).
