Python, choose logging files' directory

Question

I am using the Python logging library and want to choose the folder where the log files will be written.

For the moment, I made an instance of TimedRotatingFileHandler with the entry parameter filename="myLogFile.log". This way myLogFile.log is created on the same folder than my python script. I want to create it into another folder.

How could I create myLogFile.log into , let’s say, the Desktop folder?

Answer 2

Specify an absolute path when creating instance TimedRotatingFileHandler:

from logging.handlers import TimedRotatingFileHandler
h = TimedRotatingFileHandler('/home/user/Desktop/myLogFile.log')

or

from logging.handlers import TimedRotatingFileHandler
h = TimedRotatingFileHandler('C:\Users\user\Desktop\myLogFile.log')

Let’s say logs directory is in the parent directory of the current directory then you can use below 2 lines, to provide that location irrespective of the underlying os.

import os
log_dir = os.path.join(os.path.normpath(os.getcwd() + os.sep + os.pardir), 'logs')
log_fname = os.path.join(log_dir, 'log_file_name.log')
