Task:

Write a Python program that:

• Reads all .txt files from a directory
  You can download and use the text files in the link below.
  

• Extracts the number in each file

• Plots those numbers on a line chart using the filenames (without .txt) as labels

Expected Output:

A line graph showing numbers from each file with the file name as the x-axis label.
