Python Coding challenge - Day 623| What is the output of the following Python Code?

 

Code Explanation:

Function Definition

def repeat_double(n):

Defines a generator function named repeat_double that takes a single argument n.

The generator will yield (produce) values one at a time when iterated over.

Loop Through Range

    for i in range(n):

A for loop runs from i = 0 to i = n - 1.

range(n) generates a sequence of numbers: [0, 1, 2, ..., n-1].

Yield First Value

        yield i

yield pauses the function and returns the value of i to the caller.

The function's state is saved so it can resume from here later.

Yield Double Value

        yield i * 2

After yielding i, the function resumes and yields i * 2 (i.e., double the value).

So for each iteration, it gives two values: i and i*2.

Calling the Function and Printing

print(list(repeat_double(3)))

Calls the repeat_double generator with n = 3.

This means the loop runs for i = 0, 1, and 2.

The values yielded are:

For i = 0: yields 0, 0

For i = 1: yields 1, 2

For i = 2: yields 2, 4

These values are collected into a list using list().

Final Output

[0, 0, 1, 2, 2, 4]
