Python Coding Challenge - Question with Answer (ID -290426)

 

Explanation:

🔹 1. Function Definition

def func():

This line defines a function named func.

It does not take any arguments.

Because it uses yield, it will behave like a generator function.

🔹 2. Generator Logic (yield from)

yield from [1, 2, 3]

yield from is used to iterate over another iterable.

Here, the iterable is the list [1, 2, 3].

It will yield values one by one:

First 1

Then 2

Then 3

👉 Equivalent code:

for i in [1, 2, 3]:

    yield i

🔹 3. Calling the Function

func()

When you call func(), it does not return a list directly.

It returns a generator object.

This generator will produce values only when iterated.

🔹 4. Converting Generator to List

list(func())

list() forces the generator to run.

It collects all yielded values into a list.

So it becomes:

[1, 2, 3]

🔹 5. Printing the Output

print(list(func()))

Prints the final list generated from the generator.

\

Output will be:

[1, 2, 3]
