Excluding certain words found in list of files with list of exclusion terms

Trying to exclude certain terms from a list as shown below. I'm sure I'm missing something.

dir = r'C:\Temo'
exclude = ['test', 'Test', 'debug', 'Debug']

for item in exclude:
    new_list = [os.path.join(dir, files)
                for files in os.listdir(dir)
                if files.endswith(".csv") and item not in files]

This results in excluding only 1 term from the exclude list, although the others are present. I'm sure I'm missing something simple

You can use all() in list comprehension to filter out items. Also, you can use str.lower to not include all variations of file-names (lower/upper-case):

import os

dir = r'C:\Temo'
exclude = ['test', 'debug']

new_list = [os.path.join(dir, file)
            for file in os.listdir(dir)
            if file.endswith(".csv") and all(ex not in file.lower() for ex in exclude)]

print(new_list)
