This code snippet does the following:

1. Imports the os module:
   The os module is a standard library module in Python that provides functions to interact with the operating system.

2. Accesses files in a directory:

   • os.listdir(data_directory) retrieves a list of all entries (files and directories) in the directory specified by data_directory.
   • The list comprehension [f for f in os.listdir(data_directory) if os.path.isfile(os.path.join(data_directory, f))] filters this list to include only files:
     • os.path.join(data_directory, f) constructs the full path for each item f in the directory.
     • os.path.isfile(...) checks if the constructed path corresponds to a file. Only files are included in the resulting list.

3. Stores the filtered files in file_list:

   • The list file_list contains all files (not directories) in the specified data_directory.

4. Prints the list of files:

   • print(file_list) outputs the list of files to the console.

Explanation:

In summary, this code retrieves all file names (excluding directories) in a specified directory (data_directory) and prints them.
