Python Coding Challenge - Question with Answer (ID -260326)

 

Explanation:

🔹 1. List Initialization

clcoding = [1, 2, 3]

👉 What this does:

Creates a list named clcoding

It contains three integers: 1, 2, and 3

🔹 2. List Comprehension with Condition

print([i*i for i in clcoding if i % 2 == 0])

This is the main logic. Let’s break it into parts.

🔸 Structure of List Comprehension

[i*i for i in clcoding if i % 2 == 0]

👉 Components:

for i in clcoding

Iterates over each element in the list

Values of i will be: 1 → 2 → 3

if i % 2 == 0

Filters only even numbers

% is the modulus operator (remainder)

Condition checks:

1 % 2 = 1 ❌ (odd → skip)

2 % 2 = 0 ✅ (even → include)

3 % 2 = 1 ❌ (odd → skip)

i*i

Squares the selected number

🔹 3. Step-by-Step Execution

i Condition (i % 2 == 0) Action Result

1 ❌ False Skip —

2 ✅ True 2 × 2 = 4 4

3 ❌ False Skip —

🔹 4. Final Output

[4]
