'Parameter "self" unfilled' error in PyCharm when attempting to access method in another class

Question

I am using PyCharm. I keep getting this error "Parameter self unfilled" on all my of method calls to methods in other classes and I can't for the life of me figure it out. In this particular instance, it actually says "Parameter final_formatted_filename unfilled" because it's taking that argument as the self argument. What am I missing?

FileHandler.py

from LogHandler import LogHandler
import Main


class FileHandler:

      def format_file_name_output(self, owner_name):
          date_and_time = self.main.Main.date_and_time_snapshot()
          final_formatted_filename = (owner_name + " (" + date_and_time[0] + "_" + date_and_time[1] + ")")
          LogHandler.create_new_log(final_formatted_filename)

LogHandler.py

class LogHandler:

    def __init__(self, log_file):
        self.log_file = log_file

    def create_new_log(self, final_formatted_filename):
        self.log_file = open(final_formatted_filename + " Log.txt", 'w+', encoding='utf-8')

The last parenthesis in the last line of FileHandler.py is what is highlighted with the aforementioned error: "Parameter final_formatted_filename unfilled". My code is riddled with this error. Any help would be greatly appreciated. Thanks!

You need to create an instance of LogHandler then you can call the method create_new_log on the instance.

handler = LogHandler()
handler.create_new_log(final_formatted_filename)
