Algorithm

  1. Input:

    • Accept the path of the nested directory as input from the user or as an argument.

  2. Check if the Directory Already Exists:

    • Use the os.path.exists() function to check if the specified directory already exists.

  3. Create Directory if Not Exists:

    • If the directory doesn't exist, use the os.makedirs() function to create the nested directory along with any missing parent directories.

  4. Handle Errors:

    • Handle exceptions that may occur during the directory creation process, such as permissions issues or invalid paths.

  5. Output/Result:

    • Display a message indicating whether the directory was successfully created or if it already exists.
