Python Coding Challenge - Question with Answer (ID -270526)

Explanation:

1. Creating List x

x = [1,2]

A list containing 1 and 2 is created.

x stores the reference (address) of that list in memory.

Memory concept:

x ───► [1, 2]

2. Assigning y = x

y = x

y does not create a new list.

y points to the same list as x.

Now both variables reference the same object.

Memory concept:

x ───► [1, 2]

y ───► [1, 2]

3. Clearing the List

x.clear()

.clear() removes all elements from the existing list.

Since x and y point to the same list, the change is visible through both variables.

After clearing:

x ───► []

y ───► []

4. Printing y

print(y)

y points to the same cleared list.

So the output becomes:

[]

Final Output:

[]
