Python Coding Challenge - Question with Answer (ID -140426)

 

Explanation:

🔹 Step 1: Create Generator

x = (i*i for i in range(3))

This creates a generator object

It does NOT store values immediately

It will generate values on demand (lazy evaluation)

👉 Values it can produce:

0, 1, 4

🔹 Step 2: First sum(x)

sum(x)

Generator starts running:

0*0 = 0

1*1 = 1

2*2 = 4

👉 Total:

0 + 1 + 4 = 5

After this, generator is fully consumed (exhausted) ❗

🔹 Step 3: Second sum(x)

sum(x)

Generator has no values left

It is already exhausted

👉 So:

sum = 0

🔹 Step 4: Final Print

print(sum(x), sum(x))

👉 Output:

5 0
