Python | Custom Cycle list
While working with Python lists, we can have a problem in which we need to perform the cycle of lists. This problem looks quite straight forward and has been discussed earlier. But sometimes, we need to perform it’s variations, hence making task challenging. We can have customizations such as elements from which cycling starts and Number of elements in cycle list. Let’s discuss solution to these variation.
Method : Using
dropwhile() + cycle() + islice()
This task can be performed using combination of above functions. In this, the elements are dropped till K with
dropwhile(), then the cycle can be done using
islice() is used to restrict the count of elements in list.
The original list is : [3, 4, 5, 7, 1] The cycled list is : [7, 1, 3, 4, 5, 7, 1, 3, 4, 5, 7, 1]
