Python Coding challenge - Day 647| What is the output of the following Python Code?

 

Code Explanation:

1. Generator Function Definition

def f():

    for i in range(3):

        yield i

def f():

Defines a generator function named f.

for i in range(3):

Loops over the values 0, 1, 2.

yield i

Yields the current value of i.

This makes f() a generator, which returns an iterator when called.

2. Creating a Generator Object

g = f()

Calls the generator function f() and assigns the returned generator object to variable g.

3. Advancing the Generator Once

next(g)

Advances the generator g by one step.

i = 0 is yielded. So the generator is now paused at i = 1.

Note: This value is discarded (not printed or stored).

4. Reassigning the Generator Object

g = f()

A new generator object is created and assigned to g.

The previous generator (which had already yielded one value) is discarded.

This new g starts fresh from i = 0.

5. Converting the Generator to a List

print(list(g))

list(g) consumes the new generator fully.

It collects all yielded values: [0, 1, 2]

Output:

[0, 1, 2]

Final Output

[0, 1, 2]
