Code Explanation:
🔹 Step 1: Create List a
a = [1, 2]
A list a is created
Memory: a → [1, 2]
🔹 Step 2: Copy List using Slicing
b = a[:]
a[:] creates a shallow copy of the list
New list is created in memory
👉 Now:
a → [1, 2]
b → [1, 2] (different object)
🔹 Step 3: Modify b
b[0] = 9
Only list b is changed
a remains unchanged
👉 Now:
a → [1, 2]
b → [9, 2]
🔹 Step 4: Print Output
print(a, b)
👉 Output:
[1, 2] [9, 2]
