Program Overview

This Python program displays structured information that is easy to find and navigate.
It can be used to list files, show system details, or organize data in a readable format.
In this example, we’ll list all files in a given directory with their sizes and last modified dates.

Python Code:

import os
from datetime import datetime

# Read target directory from user
directory = input("Enter directory path: ")

# List and display file info
print("\n--- File Information ---")
for filename in os.listdir(directory):
    filepath = os.path.join(directory, filename)
    if os.path.isfile(filepath):
        size = os.path.getsize(filepath)
        modified = datetime.fromtimestamp(os.path.getmtime(filepath))
        print(f"{filename} | {size} bytes | Last modified: {modified.strftime('%Y-%m-%d %H:%M:%S')}")

Sample Output:

Enter directory path: ./docs  

--- File Information ---
report.pdf | 24567 bytes | Last modified: 2025-09-28 14:22:10  
summary.txt | 1024 bytes | Last modified: 2025-09-30 09:05:44

Step-by-Step Explanation:

- The user enters a directory path
- The program loops through all files in that directory
- For each file, it displays the name, size in bytes, and last modified timestamp
- The output is formatted for easy scanning and retrieval
