Python Coding challenge - Day 608| What is the output of the following Python Code?

 

Code Explanation:

1. Generator Function with yield from

def letters():

    yield from "abc"

This defines a generator function named letters.

yield from "abc" means: yield each character from the string "abc" one at a time.

It is a shorthand for:

for ch in "abc":

    yield ch

So, calling letters() returns a generator that yields: 'a', 'b', 'c'.

2. Enumerating the Generator

for i, ch in enumerate(letters(), start=1):

enumerate(letters(), start=1) will:

Iterate over the letters() generator.

Add a counter starting from 1.

So the loop will yield:

(1, 'a')

(2, 'b')

(3, 'c')

3. Printing Values with end=" "

    print(i, ch, end=" ")

For each (i, ch) pair, it prints:

the index (i)

the character (ch)

on the same line, separated by spaces (due to end=" ").

So it prints:

1 a 2 b 3 c 

Final Output

1 a 2 b 3 c
