How do I concatenate two lists in Python?

Example:

listone = [1, 2, 3]
listtwo = [4, 5, 6]

Expected outcome:

>>> joinedlist
[1, 2, 3, 4, 5, 6]

Answer

You can use the + operator to combine them:

listone = [1,2,3]
listtwo = [4,5,6]


joinedlist = listone + listtwo

Output:

>>> joinedlist
[1,2,3,4,5,6]
