I am trying to use python built in logging with multiprocessing. Goal -- is to have errors logged to a file called "error.log" Issue -- The errors are printed in the console instead of the log file. see code below
import concurrent.futures
from itertools import repeat
import logging
def data_logging():
error_logger = logging.getLogger("error.log")
error_logger.setLevel(logging.ERROR)
formatter = logging.Formatter('%(asctime)-12s %(levelname)-8s %(message)s')
file_handler = logging.FileHandler('error.log')
file_handler.setLevel(logging.ERROR)
file_handler.setFormatter(formatter)
error_logger.addHandler(file_handler)
return error_logger
def check_number(error_logger, key):
if key == 1:
print ("yes")
else:
error_logger.error(f"{key} is not = 1")
def main():
key_list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 1, 4, 5, 4, 3, 4, 5, 4, 3, 4, 5, 4, 3, 4, 3]
error_logger = data_logging()
with concurrent.futures.ProcessPoolExecutor(max_workers=1) as executor:
executor.map(check_number, repeat(error_logger), key_list)
if __name__ == '__main__':
main()Function check_number checks if numbers in list key_list is 1 or not if key = 1, prints yes to the console, if not i would like the program to add {key} is not = 1 to the log file. instead with the code above it prints it to the console. please help if u can. this is a mini example to my program so don't change the logic
