How to iterate through list infinitely with +1 offset each loop?

I want to infinitely iterate through the list from 0 to the end, but in the the next loop I want to start at 1 to the end plus 0, and the next loop would start at 2 to the end plus 0, 1, up to the last item where it would start again 0 to the end…

a = [ 0, 1, 2 ]
offset = 0
rotate = 0
while True:
    b = a[rotate]
    print(b)
    offset += 1
    rotate += 1
    if offset >= len(a):
        offset = 0
        rotate += 1
    if rotate >= len(a):
        rotate = 0

This is the solution I came up with so far. It’s far from perfect.

The result that I want is:

0, 1, 2 # first iteration
1, 2, 0 # second iteration
2, 0, 1 # third iteration
0, 1, 2 # fourth interation

and so on.

>Solution :

Try this:

a = [0, 1, 2]

while True:
    print(a)
    a.append(a[0])
    a.pop(0)

Output:

[0, 1, 2]
[1, 2, 0]
[2, 0, 1]
[0, 1, 2]
[1, 2, 0]
[2, 0, 1]
...

EDIT (suggested by Tomerikoo):
To remove the brackets use

a = [0, 1, 2]

while True:
    print(*a, sep=', ')
    a.append(a[0])
    a.pop(0)

Output:

0, 1, 2
1, 2, 0
2, 0, 1
0, 1, 2
1, 2, 0
2, 0, 1
