How to Double a List in Python | Python Challenge Day 11
This code snippet demonstrates how to double the contents of a list in Python using the *= operator. The initial list list1 contains three elements: [7, 8, 9]. The operation list1 *= 2 effectively repeats the list's elements, concatenating the list with itself. This operation modifies list1 to now contain six elements: [7, 8, 9, 7, 8, 9]. The print(list1) statement then outputs the updated list: [7, 8, 9, 7, 8, 9].
