Python Extend List when declaring list

Question

In Javascript, I can do something like this let list = [1, 2, 3] let list2 = [4, 5, 6, ...list] And that resulting list would be [4,5,6,1,2,3] Is there any way to do this in Python without having to call extend() or using the += after declaring a list? Select the correct answer from above options

Answer 1

Use the following syntax: list2 = [4, 5, 6, *list] Once the elements of my first list are unpacked, one after another, in the same order they appear in the original list. Before 3.5, the best solution is as shown below: list2 = [4, 5, 6] + list which is still the one-liner, but has to construct the temporary list first, then concatenate a two of them and throw away the temporary.
