I'm trying to make a logger, which will create a new .log file every time the code is executed. The .log file should have the following format info_24/03/2017_13:00:00.log. I'm trying to achieve this with strftime however an error is raised when I try to run the code.
#!/usr/bin/python3 import logging from time import strftime def main(): datestr = strftime('[%d/%m/%Y %T]') logfile = 'info_{}.log'.format(strftime('%d/%m/%Y_%T')) logformat = '%(asctime)s %(levelname)s %(message)s' logging.basicConfig(filename=logfile, filemode='w', level=logging.INFO, format=logformat, datefmt=datestr) print('Hello world!') logging.info('Program executed') if __name__ == '__main__': main() When I remove strftime from filename, program runs okay. Obviously though, it doesn't have the desired effect. Otherwise, here's the error.
Traceback (most recent call last): File "./log_example.py", line 16, in <module> main() File "./log_example.py", line 10, in main logging.basicConfig(filename=logfile, filemode='w', level=logging.INFO, format=logformat, datefmt=datestr) File "/usr/lib/python3.5/logging/__init__.py", line 1744, in basicConfig h = FileHandler(filename, mode) File "/usr/lib/python3.5/logging/__init__.py", line 1008, in __init__ StreamHandler.__init__(self, self._open()) File "/usr/lib/python3.5/logging/__init__.py", line 1037, in _open return open(self.baseFilename, self.mode, encoding=self.encoding) FileNotFoundError: [Errno 2] No such file or directory: '/home/estilen/Dropbox/College/Year_3/CSA2/Python/Examples/Logging/info_24/03/2017_13:04:29.log' I'm aware of rotating log files, but I wanted to get this to work anyway. How do I go about fixing the code to achieve my goal?
