Logging into single file from multiple modules in python when TimedRotatingFileHandler is used
by Chethan Kumar S June 27, 2022

June 27, 2022

Hi all, Need help with below query on python logging module. I have a main process which makes use of different other modules. And these modules also use other modules. I need to log all the logs into single log file. Due to use of TimedRotatingFileHandler, my log behaves differently after midnight. I got to know why it is so but couldn't get how I can solve it. Issue was because of serialization in logging when multiple processes are involved. Below is log_config.py which is used by all other modules to get the logger and log. import logging import sys from logging.handlers import TimedRotatingFileHandler FORMATTER = logging.Formatter("%(asctime)s — %(name)s — %(message)s") LOG_FILE = "my_app.log" def get_file_handler(): file_handler = TimedRotatingFileHandler(LOG_FILE, when='midnight') file_handler.setFormatter(FORMATTER) return file_handler def get_logger(logger_name): logger = logging.getLogger(logger_name) logger.setLevel(logging.DEBUG) # better to have too much log than not enough logger.addHandler(get_file_handler()) #with this pattern, it's rarely necessary to propagate the error up to parent logger.propagate = False return logger All other modules call, 'logging = log_config.get_logger(name)' and use it to log. I came to know about QueueHandler and QueueListener but not sure how to use them in my code. How can I use these to serialize logs to single file.? Any help is appreciated. Thanks, Chethan

Subtract n months from datetime
by Paulo da Silva June 27, 2022

June 27, 2022

Hi! I implemented a part of a script to subtract n months from datetime. Basically I subtracted n%12 from year and n//12 from the month adding 12 months when it goes<=0. Then used try when converting to datetime again. So, if the day is for example 31 for a 30 days month it raises a ValuError exception. Then I subtract 1 to day and repeat. The code seems too naive and very very complicated! What is the best way to achieve this? Any existent module? At the very end, what I want is to subtract nx where x can be y, m, w, d for respectively years, months, weeks or days. I feel I am missing something here ... Thanks. Paulo
