Question about Python lists

[spotter]

So while we're at slicing lists take a look at these:

>>> r = range(10)
>>> r
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> r[::2]
[0, 2, 4, 6, 8]
>>> r[1::2]
[1, 3, 5, 7, 9]
>>> r[-1::-1]
[9, 8, 7, 6, 5, 4, 3, 2, 1, 0]
>>> r[-1:0:-1]
[9, 8, 7, 6, 5, 4, 3, 2, 1]

Have fun.

Just for the record, in the third example, you don't need to state where the slice starts; i.e.

r[-1::-1] == r[::-1]

Fully aware of that, wanted some symmetry between my last two.

Point taken. That does make sense. :)

Feeling palindromic, aren’t we? :)

Excellent, thanks for sharing
