How To Add Two Lists In Python?

In Python, you can add two lists together using the + operator. This concatenates the lists, creating a new list containing the elements of both lists. Here’s an example:

list1 = [1, 2, 3]
list2 = [4, 5, 6]

result = list1 + list2
print(result)

Output:

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

This adds the elements of list2 to the end of list1, creating a new list.

Alternative: Using extend()

You can also use the extend() method to add elements of one list to another. This modifies the original list in place:

list1 = [1, 2, 3]
list2 = [4, 5, 6]

list1.extend(list2)
print(list1)

Output:

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

This method modifies list1 by adding the elements of list2 to it.
