What is the output of this code that demonstrates list concatenation and the use of the plus operator?

list1 = [1, 2, 3]
list2 = [4, 5, 6]
result = list1 + list2
print(result)

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

  2. [5, 7, 9]

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

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

Show answer & explanation

Correct answer

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

Explanation

The plus operator concatenates two lists by creating a new list containing all elements from both lists in order.
