Python Coding Challenge - Question with Answer (ID 090926)

Explanation:

1. range(5)

range(5)

generates numbers from 0 to 4:

0, 1, 2, 3, 4

2. Dictionary Comprehension

x = {i: i % 3 for i in range(5)}

Here:

i → dictionary key

i % 3 → dictionary value

Let's calculate each value:

i i % 3 Key → Value

0 0 0: 0

1 1 1: 1

2 2 2: 2

3 0 3: 0

4 1 4: 1

Therefore:

x = {0: 0, 1: 1, 2: 2, 3: 0, 4: 1}

3. Accessing x[2]

x[2]

The key 2 has value:

x[2] = 2

4. Accessing x[4]

x[4]

The key 4 has value:

x[4] = 1

because:

4 % 3 = 1

5. Adding the Values

x[2] + x[4]

becomes:

2 + 1 = 3

6. print() Statement

print(x[2] + x[4])

prints the calculated result:

3

✅ Final Output

3
