Delete Lines that Contain Words - Loop through files in a folder - Write to new files

[dj99]

Hi friends,

I am trying to loop through files and from each file delete the lines that contain the search keywords

import os

def remove_line_from_file(filename, line_to_remove, dirpath=''):
  
    filename = os.path.join(dirpath, filename)
    temp_path = os.path.join(dirpath, 'temp.txt')


    
    with open(filename, 'r') as f_read, open(temp_path, 'w') as temp:


        search_keywords=['Car','Train']                # Delete all sentences that contain these words
        
        for line in f_read:
            if (any(map(lambda word: word in line, search_keywords))):
                    
                if line.strip() == word:            #f line.strip() == line_to_remove:
                    continue
                temp.write(line)

        os.remove(filename)
        os.rename(temp_path, filename)
        directory = 'C:/Users/Home/Desktop/test/'
        dirpath, _, files = next(os.walk(directory))

        for f in files:
            remove_line_from_file(f, line, dirpath)

I dont get an error as such - but I cant work out why it doesnt work.

It may not be syntactically correct as i borrowed code from here and there.

Please may a kind person have a look at this

thank you for your time and help
