title: Iteration over list with shifting starting point
body: <p>Using Python3, I need to iterate over the list of elements sequentially starting from an arbitrary i (i &lt;= 6), complete the full iteration cycle, repeat it starting with i += 1 and so on.  This cycle should not end. In content, this is the getting of the names of the days of the week, starting with the current one. For example, if today is Wednesday, as a result of iterations I have to get a list [Wednesday, Thursday, Friday, Saturday, Sunday, Monday, Tuesday]. It seems to be quite simple, but I am at a dead end. I will be grateful for the hint or help.</p>
