Python Coding challenge - Day 268| What is the output of the following Python Code?

 Step-by-Step Explanation:

list1 = [1, 2, 3]:

A list [1, 2, 3] is created and assigned to list1.

list2 = list1:

list2 is assigned to reference the same list object as list1.

Both list1 and list2 now refer to the same object in memory.

list2.append(4):

The append(4) method modifies the list in place, adding the value 4 to the end of the list.

Since list1 and list2 refer to the same list, this change is reflected in both variables.

print(list1):

The list now contains [1, 2, 3, 4] because the modification affected the original list object.

Final Output:

[1, 2, 3, 4]
