Python Coding challenge - Day 645| What is the output of the following Python Code?

 

Code Explanation:

1. Generator Expression Assigned to x

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

This creates a generator object that will yield values of i * i (i.e., square of i) for i in [0, 1, 2].

No values are computed yet — it's lazy evaluation.

So x is now a generator that will yield 0, then 1, then 4.

2. First next(x) Call

print(next(x))

This gets the next value from the generator x.

At this point, the generator yields 0 * 0 = 0.

So this line prints:

0

3. Second next(x) Call

print(next(x))

Now the generator continues from where it left off (i = 1).

It yields 1 * 1 = 1.

So this prints:

1

4. Reassign Generator to x Again

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

This replaces the original generator with a new one.

So now x is reset, and will again yield 0, then 1, then 4.

5. Third next(x) Call

print(next(x))

This uses the new generator, starting over from the beginning.

So it again yields 0 * 0 = 0.

This prints:

0

Final Output

0

1

0
