Question

How do I concatenate two lists in Python?

Example:

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

Expected outcome:

>&g         


        

Answer 1

 a=[1,2,3]
 b=[4,5,6]

 c=a+b
 print(c)

OUTPUT:

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

In the above code "+" operator is used to concatenate the 2 lists into a single list.

ANOTHER SOLUTION:

 a=[1,2,3]
 b=[4,5,6]
 c=[] #Empty list in which we are going to append the values of list (a) and (b)

 for i in a:
     c.append(i)
 for j in b:
     c.append(j)

 print(c)

OUTPUT:

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