Concatenate two lists in Python?

In Python, you can concatenate two lists using the + operator or the extend() method.

Here’s an example using the + operator:

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

In this example, we create two lists list1 and list2, and then concatenate them using the + operator to create a new list concatenated_list.

Alternatively, you can use the extend() method to append the elements of one list to another:

list1 = [1, 2, 3]
list2 = [4, 5, 6]
list1.extend(list2)
print(list1)

In this example, we use the extend() method to append the elements of list2 to list1.

Note that when using the + operator, a new list object is created, whereas with extend() the original list is modified in place.
