[SOLVED] OSError: [Errno 22] Invalid argument - Panda - Jun-03-2018
When trying to write to a log file, i get the error OSError: [Errno 22] Invalid argument
The code i am using is as follows:
import datetime
import logging
logger = logging.getLogger('k')
hdlr = logging.FileHandler('Path to the log file/Logs/log'+str(datetime.datetime.now())+'.log')
formatter = logging.Formatter('At %(asctime)s, the program returned %(message)s at level %(levelname)s
hdlr.setFormatter(formatter)
logger.addHandler(hdlr)
logger.setLevel(logging.INFO)
logger.info('Hello')

Does the 'Path to the log file' directory exists in your working directory?

Yes
RE: OSError: [Errno 22] Invalid argument - wavic - Jun-03-2018
You have a directory called 'Path to the log file' and its subdir 'Logs'?
Post the full error traceback in error tags, please.

I presume that you are following some book or tutorial.
On line 4 in your code, instead of 'Path to the log file' put your path 'C:/Users/Richard/Desktop/Atom/K'.
hdlr = logging.FileHandler(''C:/Users/Richard/Desktop/Atom/K/Logs/log'+str(datetime.datetime.now())+'.log')

hdlr = logging.FileHandler(''C:/Users/Richard/Desktop/Atom/K/Logs/log'+str(datetime.datetime.now())+'.log')
That is what is there. I still get the error.

Yea I left one quote when I pasted it. The path to the file is not 'Path to the log file/Logs' but 'C:/Users/Richard/Desktop/Atom/K/Logs'
hdlr = logging.FileHandler('C:/Users/Richard/Desktop/Atom/K/Logs/log'+str(datetime.datetime.now())+'.log')If you give you an error post it.

Perhaps you don't understand. This was there the entire time. I just didn't say the full path.

the colon is not allowed in file name. Use something like
hdlr = logging.FileHandler('Path to the log file/Logs/log{}.log'.format(datetime.datetime.strftime(datetime.datetime.now(), '%Y%m%d%H%M%S_%f'))
