How do I concatenate two lists in Python?

Here how we do concatenate two lists in Python.

Concatenation of a list means joining two different lists. And if we want to concatenate two lists in python we have to use an operator. That operator is ‘+ ‘. We have to use the plus operator if we want to contact two lists. 

use of the + the operator is as follow:

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

So here we will have an output as :

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