The main problem with Python lists is that they are not ordered. This can be a problem when you want to do something like find the fifth item in a list.
list1 = [1, 2, 3] list2 = [4, 5, 6] list3 = list1 + list2 print(list3)
This code creates two lists, list1 and list2, each containing three elements. It then creates a third list, list3, which contains the elements of list1 and list2 concatenated. Finally, it prints the contents of list3.
Concatenate lists options
There are a few ways to concatenate lists in Python. The simplest way is to use the + operator:
list1 = [1, 2, 3] list2 = [4, 5, 6] list3 = list1 + list2
This will create a new list containing the items from both lists combined. You can also use the * operator to combine multiple lists into one:
list1 = [1, 2, 3] list2 = [4, 5, 6] list3 = list1 * list2
