Python Coding Challenge - Question with Answer (ID 100926)

 

Explanation:

1. Creating the Generator

g = (x for x in range(10) if x % 2 == 0)

This is a generator expression.

range(10) gives:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

The condition:

x % 2 == 0

keeps only the even numbers.

So the generator will produce:

0, 2, 4, 6, 8

⚠️ Important: A generator does not create the complete list immediately. It produces values one at a time when requested.

2. First next(g)

next(g)

The first value generated is:

0

So:

next(g) → 0

3. Second next(g)

next(g)

The generator continues from where it stopped.

The next even number is:

2

So:

next(g) → 2

4. Third next(g)

Again, the generator continues forward.

The next value is:

4

So:

next(g) → 4

5. Adding the Values

Now the expression becomes:

0 + 2 + 4

Therefore:

6

6. print() Statement

print(next(g) + next(g) + next(g))

prints:

6

✅ Final Output

6
