Python Coding challenge - Day 636| What is the output of the following Python Code?

 

Code Explanation:

1. Function Definition

def flaggen(data):

Defines a function named flaggen that takes one argument data.

data is expected to be an iterable, like a list or string.

2. Loop Through Input Data

    for i in data:

Iterates over each element i in the input data.

3. Conditional Check and Yield

        if i == 'x':

            yield 'FOUND'

        else:

            yield i

yield is used instead of return, so this function is a generator.

If the element is 'x', it yields 'FOUND'.

Otherwise, it yields the element i unchanged.

This creates a new iterable where 'x' is replaced by 'FOUND'.

4. Function Call and List Conversion

print(list(flaggen(['a', 'x', 'b'])))

Calls flaggen with the list ['a', 'x', 'b'].

Converts the generator it returns into a list using list(...).

Iteration happens:

'a' → not 'x' → yields 'a'

'x' → equals 'x' → yields 'FOUND'

'b' → not 'x' → yields 'b'

Final output: ['a', 'FOUND', 'b']

Final Output

['a', 'FOUND', 'b']
