[Python] Python logging object is being accumulating on each instantiation

Consider the following code, where I have created a custom logger class and then in a for loop I am creating logger object multiple times, but instead of adding one log at a time it is adding multiple logs as shown below

import sys
import logging
import os

import configs

class Logger:
def __init__(self, logger_name='logger', log_file_name='logs.log'):
logger = logging.getLogger(logger_name)
logger.setLevel(logging.DEBUG)

formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')

file_handler = logging.FileHandler(os.path.join(configs.LOGS_DIR, log_file_name))
file_handler.setLevel(logging.INFO)
file_handler.setFormatter(formatter)
logger.addHandler(file_handler)

self.logger = logger

def get_logger(self):
return self.logger

for i in range(5):
logger = Logger(logger_name=f'test', log_file_name='test').get_logger()
logger.info(i)


I was expecting this:

2024-12-20 21:17:09,623 - test - INFO - 0
2024-12-20 21:17:09,623 - test - INFO - 1
2024-12-20 21:17:09,623 - test - INFO - 2
2024-12-20 21:17:09,623 - test - INFO - 3
2024-12-20 21:17:09,642 - test - INFO - 4


but this is the output:

2024-12-20 21:17:09,623 - test - INFO - 0
2024-12-20 21:17:09,623 - test - INFO - 1
2024-12-20 21:17:09,623 - test - INFO - 1
2024-12-20 21:17:09,623 - test - INFO - 2
2024-12-20 21:17:09,623 - test - INFO - 2
2024-12-20 21:17:09,623 - test - INFO - 2
2024-12-20 21:17:09,623 - test - INFO - 3
2024-12-20 21:17:09,623 - test - INFO - 3
2024-12-20 21:17:09,623 - test - INFO - 3
2024-12-20 21:17:09,623 - test - INFO - 3
2024-12-20 21:17:09,642 - test - INFO - 4
2024-12-20 21:17:09,642 - test - INFO - 4
2024-12-20 21:17:09,642 - test - INFO - 4
2024-12-20 21:17:09,642 - test - INFO - 4
2024-12-20 21:17:09,642 - test - INFO - 4


Why this is happening and how to fix this?
