How to concatenate two lists in Python?

Question

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 1

listone.extend(listtwo)

This will extend or add all the elements of listtwo to listone. That is, listone will be [1,2,3,4,5,6,7,8].

Answer 2

listone+listtwo will do it

So you can test it yourself:

a=[1,2,3,4,5,6,7,8]

b=[9,10]

print (a+b)
