Project 3 - File name convention checker

In project 3, I wrote a Python script that reads all the filenames and checks if the name is correct or not. The name is correct when it has a specific word in front of it. Then it makes a list of the correct and the incorrect files and gives an error so you know which file names to fix.

The code to check the filenames	The result, sorted filenames

The code to check the filename:

import os
import sys

folder_path = "projects/project3/TestFiles"
file_list = os.listdir(folder_path)

good_files = []
bad_files = []
for file_name in file_list:
    file_path = os.path.join(folder_path, file_name)
    if os.path.isfile(file_path):
        if file_name.startswith('BusinessRule_ba_'):
            good_files.append(file_path)
        else:
            bad_files.append(file_path)
if good_files:
    print("These are correct:")
    for good_file in good_files:
        print(good_file)
else:
    print("No correct filenames found.")
if bad_files:
    print("\nThese are bad:")
    for bad_file in bad_files:
        print(bad_file)
    print("\nError: We found files that violate the naming convention")
    sys.exit(1)

else:
    print("\nAll filenames are correct.")
