Python Coding challenge - Day 614| What is the output of the following Python Code?

 

Code Explanation:

1. Generator Function letters()

def letters():

    yield from ['x', 'y']

This defines a generator function named letters.

yield from ['x', 'y'] tells the generator to yield each item from the list ['x', 'y'].

So, when you call letters(), it will generate 'x', then 'y'.

2. Generator Function numbers()

def numbers():

    yield from [1, 2]

Similar to the previous one, this defines a generator function numbers.

It yields 1, then 2.

3. Using zip to Pair Generator Outputs

z = zip(letters(), numbers())

zip() takes two iterable objects and pairs their elements one by one into tuples.

Since both letters() and numbers() return generators, zip() will combine:

'x' from letters() with 1 from numbers() → ('x', 1)

'y' from letters() with 2 from numbers() → ('y', 2)

4. Convert the Zipped Result to a List and Print

print(list(z))

list(z) forces the evaluation of the generator and converts the output to a list:

[('x', 1), ('y', 2)]

print(...) displays this list on the screen.

Final Output

[('x', 1), ('y', 2)]
