shouldn't this be s = pd.Series instead of s = Series? I made this change above, but a bit concerned that it isn't failing in master.

how is Series in the namespace? it it getting it from the file namespace? if so, why bother with importing pd?

I guess my concern is that it is passing because it isnt actually testing what its supposed to
