Actually, I found : very clear as a newcomer to Python -- and you might laugh at me for this -- because it corresponded with my visualization of slices as, literally, vertical 'cuts' in the list.
On the contrary, I have advised people for years (in c.l.p posts) to realize that 0,1,...n-1,n number the n+1 slice positions before, between, and after the n items, which correspond to the possible positions of vertical bar cursors.
: is symmetrical and straight up-and-down, and for whatever reason this is what works for me when trying to visualize the slice.
Thanks for pointing out that : is as close to | as possible in essential characteristics without being |. (The latter, of course, already being used for bitwise not and in other languages, doubled for logical not.) tjr
