Python Coding Challange - Question with Answer (01210925)

 

Sure 👍 Let’s carefully break this code down step by step:

---

🧩 Code:

a = [i**2 for i in range(6) if i % 2]
print(a)

---

🔹 Step 1: Understanding range(6)

range(6) generates numbers from 0 to 5:

[0, 1, 2, 3, 4, 5]

---

🔹 Step 2: Condition ifi % 2

• i % 2 means remainder when i is divided by 2.

• If the remainder is not 0, it’s an odd number.

• So only odd numbers are kept:

[1, 3, 5]

---

🔹 Step 3: Expression i**2

• For each remaining number, calculate its square (i**2).

1**2 = 1 

3**2 = 9 

5**2 = 25

---

🔹 Step 4: Final List

So, the list comprehension produces:

a = [1, 9, 25]

---

🔹 Step 5: Printing

print(a) outputs:

[1, 9, 25]

---

✅ This is a list comprehension that filters odd numbers from 0–5 and squares them.
