Challenge Yourself! 🚀

Before checking the solution, try building a script that scans a folder and renames each .txt file by adding today's date at the end.

Task:

Write a Python program that:

• Goes through each .txt file in a directory

• Appends the current date to the filename
  For example, file a.txt should be renamed to a-2025-5-8.txt (existing_name-YYYY-MM-DD.txt)

• You can download and use these sample files and place them in a directory named “files”.

Expected Output:
The console will display the old and new names of each file.

And here is how the renamed files look like:
