Is there a way to loop or iterate through a list/tuple in such a way

example, suppose I define a list "daysOfWeek" such that:
daysOfWeek = ['sunday', 'monday', 'tuesday', 'wednesday', 'thursday', 'friday',
'saturday']

Help on class cycle in module itertools:
class cycle(__builtin__.object)
| cycle(iterable) --> cycle object

| Return elements from the iterable until it is exhausted.
| Then repeat the sequence indefinitely.
