I'm getting the following error in my python code. Can you help me understand where I am going wrong? This is the error "The call rotate([0, 1, 3, 5]) returns [5, 0, 1, 3], not None.
def rotate(alist):
"""
Rotates the contents of alist one element to the right.
Rotating a list to the right pushes all elements to the right, and makes
the previously last element the new first element.
Examples:
If a = [0,2,3,4], rotate(a) makes a = [4,0,2,3]
If a = [1], rotate(a) makes a = [1]
Parameter a: The list to rotate
Precondition: a non-empty list
"""
rotate_alist = []
for a in range(len(alist)):
rotate_alist.append(alist[(a-1) % len(alist)])
return rotate_alist
