How to perform a cyclic shift by n steps?

Question

Python

Hey!
unable to rotate n steps
Example:

s = 2
a = 'hello'
print (a[s:] + a[:-s])

The answer should be like this: lohel Tell me
, please, where is the mistake?
Found the answer:
print (a[-s::]+a[:-s])

Answer 1

print (a[len(a)-s:] + a[:-s]) or
just
print (a[-s:] + a[:-s])
the element that will be the first, and the final position - the element that will be FOR the last is indicated.
What would work with any step is useful offset normalize modulo length:
s %= len(a)
print (a[-s:] + a[:-s])
