Python Coding Challenge - Question with Answer (ID 220726)

 

Code Explanation:

📌 Heading 1: Create the Original List

a = [1, 2]

Explanation

Creates a list named a.

The list contains two elements: 1 and 2.

📌 Heading 2: Create a Copy of the List

b = a.copy()

Explanation

copy() creates a new list with the same elements.

b is independent of a.

Both lists have identical values but different memory locations.

📌 Heading 3: Add a New Element

b.append(3)

Explanation

append() adds the value 3 to the end of list b.

Only b changes because it is a separate copy.

The original list a remains unchanged.

📌 Heading 4: Print the Original List

print(a)

Explanation

Prints the contents of the original list a.

Since only b was modified, a still contains its original values.

📌 Output

[1, 2]
