How to get a slice in Python to the right?

Question

Python

I recently started learning python and got to slices. Given a list.
1 2 3 4 5
From it we get
2 3 4 5 0
That's how
a = a[1:] + [0]
And how to get it?
0 1 2 3 4

Answer 1

Well, for example like this:
[0] + a[:-1]

Answer 2

If no cuts:
[i-1 for i in a]
