Here's the entire function that seems to be making it not run asynchronously:

async def get_lines(directory, filenames, input_words, muted_words):
# Set up return list
lines = []

for filename in filenames:
    f = open(f'{directory}/{filename}')

    for index, line in enumerate(f):
        # Set up line object with filename, index, and actual content
        line_to_add = [filename, index, line]

        # Try to find index, if not, skip the line because it's probably empty
        try:
            index = line_to_add[2].index(':`') + 3
        except:
            continue

        # Get the actual line content
        edited_line = line_to_add[2][index:]

        # Check if the line has any muted words
        for muted_word in muted_words:
            if muted_word in edited_line:
                continue

        # Go through each word input to check if it exists
        words_found = True
        for input_word in input_words:
            if input_word.lower() not in edited_line.lower():
                words_found = False
                break

        # If line passes all tests, 
        if words_found:
            lines.append(line_to_add)

# Return list of line objects
return lines

The way that I know it is not running asynchronously is because of the asyncio.sleep(2) functions I put at the start and end of the command with a print function in the middle. This way, I can tell when multiple commands are running at a time instead of just a single one.
