Python - Join Lists

There are several ways to join, or concatenate, two or more lists in Python. One of the easiest ways are by using the + operator.

list1 = ["a", "b", "c"] list2 = [1, 2, 3]

Another way to join two lists is by appending all the items from list2 into list1, one by one:

list1 = ["a", "b" , "c"] list2 = [1, 2, 3] for x in list2: list1.append(x)

method, where the purpose is to add elements from one list to another list:

method to add list2 at the end of list1: list1 = ["a", "b" , "c"] list2 = [1, 2, 3] list1.extend(list2)
