Is there a way to overwrite log files in python 2.x
I'm using python2.x logging module, like,
logging.basicConfig(format='%(asctime)s %(message)s',
datefmt='%m/%d/%Y %I:%M:%S %p',
filename='logs.log',
level=logging.INFO)
I want my program to overwrite logs.log file for each execution of the script, currently it just appends to old logs.
I know the below code will overwrite, but if there is a way to do it via logging config, it'll look better.
with open("logs.log", 'w') as file:
pass
python-2.7 logging

Add the filemode option to basicConfig:
logging.basicConfig(format='%(asctime)s %(message)s',
datefmt='%m/%d/%Y %I:%M:%S %p',
filename='logs.log',
filemode='w',
level=logging.INFO)
From the logging documentation for the basicConfig method (in the big table explaining all options):
filemode: Specifies the mode to open the file, if filename is specified (if filemode is unspecified, it defaults to ‘a’).

Note that "filemode" is the keyword "mode" if you use DictConfig. Example: ` "handlers": { "file": { "class": "logging.FileHandler", "formatter": "form02", "level": "INFO", "filename": "logs.log", "mode": "w", # Overwrite file if it exists }, }, `

Both

and
logging.basicConfig(format='%(asctime)s %(message)s',

logging.basicConfig(format='%(asctime)s %(message)s',
datefmt='%m/%d/%Y %I:%M:%S %p',

and
logging.basicConfig(format='%(asctime)s %(message)s',
datefmt='%m/%d/%Y %I:%M:%S %p',
filename='logs.log',
filemode='w+',
level=logging.INFO)
always append in Python 2.7, on both Windows and Linux

I'm also seeing the same behavior in Python 3.6. This just doesn't seem right- I'm passing filemode='w' in all cases.
