[Tutor] referring to list elements

[Christopher Smith]

Can someone educated in comp sci tell me whether you really refer to the
elements of a list, when speaking, as zero-eth, one-eth, two-eth, etc...,
as described in the How to Think book?  What do you do when you get to the
fifth element: do you call it the four-eth element?  If you refer to them
in the natural linguistic sense as '1st', '2nd', etc..., are you always
doing a little mental gymnastics to remember that the index is one less
than the actual element position in the ordinal sense?

['1st','2nd','3rd','4th','5th'] #indices [0,1,2,3,4]
