Python Coding Challenge - Question with Answer (ID -230626)

 

Explanation:

Line 1

clcoding = map(str, [1, 2, 3])

Step 1: List Creation

[1, 2, 3]

A list containing three integers is created:

Index Value

0 1

1 2

2 3

Step 2: str Function

str

str() is a built-in Python function that converts a value into a string.

Examples:

str(1)   # '1'

str(2)   # '2'

str(3)   # '3'

Step 3: map() Function

map(str, [1, 2, 3])

Syntax:

map(function, iterable)

Here:

Function → str

Iterable → [1, 2, 3]

Python will apply str() to every element of the list.

Conceptually:

1 → '1'

2 → '2'

3 → '3'

Result:

['1', '2', '3']

But map() does not create the list immediately.

It creates a map object (iterator).

So:

clcoding

stores:

<map object>

Line 2

print(next(clcoding))

Step 1: next()

next() retrieves the next value from an iterator.

Syntax:

next(iterator)

Since clcoding is a map iterator:

next(clcoding)

fetches the first converted value.

Internally:

1 → str(1) → '1'

Returned value:

'1'

Step 2: print()

print('1')

prints:

1

(Output appears without quotes.)

Output

1
