Python Coding Challenge - Question with Answer (ID -180426)

 

Explanation:

🔹 Step 1: Create List

x = [1, 2, 3]

A list is created

👉 x = [1, 2, 3]

🔹 Step 2: Start Loop

for i in x:

Python starts iterating over the list by index internally

Initial state:

Index → 0 → value = 1

🔹 Step 3: First Iteration

x.remove(i)   # i = 1

Removes 1 from list

👉 Now:

x = [2, 3]

⚠️ Important:

List size changed during iteration

Next index moves to index 1

🔹 Step 4: Second Iteration (Tricky Part 😈)

Now loop goes to index 1

Current list is [2, 3]

👉 Index 1 → value = 3

👉 2 gets skipped!

x.remove(3)

👉 Now:

x = [2]

🔹 Step 5: Loop Ends

No more elements to iterate

Loop stops

🔹 Step 6: Final Print

print(x)

👉 Output:

[2]
