Python Coding challenge - Day 748| What is the output of the following Python Code?

 

Code Explanation:

1. Importing Modules

import os

from pathlib import Path

os → Provides functions for interacting with the operating system (like checking if files exist).

pathlib.Path → A modern way to handle filesystem paths as objects (instead of plain strings).

2. Creating a Path Object

p = Path("sample.txt")

Creates a Path object pointing to "sample.txt".

At this point, no file is created yet — it’s just a path representation.

3. Writing to the File

p.write_text("Hello")

Creates the file "sample.txt" (if it doesn’t exist).

Writes the string "Hello" into the file.

Returns the number of characters written (in this case, 5).

4. Checking File Existence & Size

print(os.path.isfile("sample.txt"), p.stat().st_size)

os.path.isfile("sample.txt") → Returns True if "sample.txt" exists and is a regular file.

p.stat().st_size → Gets metadata of the file (stat) and fetches its size in bytes.

"Hello" is 5 characters → size = 5 bytes.

Output will be:

True 5

5. Deleting the File

p.unlink()

Removes (deletes) the file "sample.txt".

After this line, the file no longer exists on disk.

Final Output

True 5
