Algorithm

  1. Import the necessary module:

    • import os

  2. Get the directory path from the user or specify it:

    • directory_path = input("Enter the directory path: ")

  3. Check if the specified path is a valid directory:

    • if os.path.isdir(directory_path):

  4. Initialize an empty list to store the names of .txt files:

    • txt_files = []

  5. Use the os.listdir() function to get a list of all files in the directory:

    • for file_name in os.listdir(directory_path):

  6. Check if each file has a .txt extension:

    • if file_name.endswith(".txt"):

  7. If it does, add the file name to the list:

    • txt_files.append(file_name)

  8. After the loop, print or return the list of .txt files:

    • print("Text files in the directory:", txt_files)

  9. If the specified path is not a valid directory, print an error message:

    • else:
      • print("Invalid directory path.")
