Print Latest element of list with out indexing

Question

Colors = ["yellow", "red", "green"]

I'm looking for new way to given the latest element of list. Is there a way without using of index [-1]?

You should probably giving a bit of context. Would `Colors[3]` be a valid answer? — jochen, Nov 17 '21 at 15:19

I think your `Colors` needs a bit of [`pop`](https://www.programiz.com/python-programming/methods/list/pop) — Sayandip Dutta, Nov 17 '21 at 15:21

You can call next on the reversed list:

next(reversed(Colors))
# 'green'

Providing more context would help, as you could simply use Colors[len(Colors) - 1], but that still uses indexing. Another solution would be Colors.pop(), but keep in mind it will remove the last element.

In python, list class provides a function pop(), You can use Colors.pop()

But that changes/mutates the list. – user2390182 Nov 17 '21 at 15:23
@user2390182 yes it does maybe he can create a copy of the list first or he can use your solution too – Thekingis007 Nov 17 '21 at 15:25

How about this?

last = None
for x in Colors:
    last = x
print last

in this case the variable x isn't really necessary, you can do `for last in Colors: pass` for the same effect, but I guess is alright for extra clarity... – Copperfield Nov 17 '21 at 15:37
