Functions : What will this code output?

 

def my_generator():

    for i in range(3):

        yield i

gen = my_generator()

print(next(gen))

print(next(gen))

Explanation:

1. my_generator():
   • This defines a generator function that yields values from 0 to 2 (range(3)).
2. gen = my_generator():
   • Creates a generator object gen.
3. print(next(gen)):
   • The first call to next(gen) will execute the generator until the first yield statement.
   • i = 0 is yielded and printed: 0.
print(next(gen)):
• The second call to next(gen) resumes execution from where it stopped.
• The next value i = 1 is yielded and printed: 1.

Output:

0

1

If you call next(gen) again, it will yield 2. A fourth call to next(gen) would raise a StopIteration exception because the generator is exhausted.
