Question

logging.debug(\         


        

Answer 1

Maximas is right. File path is relative to execution environment. However instead of writing down the absolute path you could try the dynamic path resolution approach:

filename = os.path.join(os.path.dirname(os.path.realpath(__file__)), 'ram.log')
logging.basicConfig(filename=filename, level=logging.DEBUG)

This assumes that ram.log resides in the same directory with the one that contains the above code (that's why __file__ is used for).

Answer 2

import logging

class LogGen:
    @staticmethod
    def loggen():
        logger = logging.getLogger()
        fhandler = logging.FileHandler(filename='.\\logs\\automation.log', mode='a')
        formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
        fhandler.setFormatter(formatter)
        logger.addHandler(fhandler)
        logger.setLevel(logging.INFO)
        return logger

I can't remember where I got this otherwise I would have provided a link. But had the same problem some time ago using in jupyter notebooks and this fixed it:

import logging
logger = logging.getLogger()
fhandler = logging.FileHandler(filename='mylog.log', mode='a')
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
fhandler.setFormatter(formatter)
logger.addHandler(fhandler)
logger.setLevel(logging.DEBUG)

Answer 4

The answer why this error happens is this:

The call to basicConfig() should come before any calls to debug(), info() etc.

If you do so the basicConfig can not create and write a new file. Here I called logging.info() right before logging.basicConfig().

Don't:

import logging
logging.info("root") # call to info too early
logging.basicConfig(filename="rec/test.log", level=logging.DEBUG) # no file created

I encountered same issue and found none of the answers previously provided here would work. Maybe this issue had been solved long ago to Ramnath Reddy, but I could not find the correct answer anywhere online.

Luckily, I found a solution from a colleague's code by adding the following lines before logging.basicConfig().

Remove all handlers associated with the root logger object.

for handler in logging.root.handlers[:]:
    logging.root.removeHandler(handler)

Try and see if it helps for whomever had the same issue.

This does create a log within the pycharm terminal using the Py terminal within it. You need to check the location of where the terminal is (try dir on Windows or pwd on linux/mac). Instead of just putting in ram.log, use the full file path of where you would like the file to appear. E.G.

logging.basicConfig(filename='/Users/Donkey/Test/ram.log', level=logging.DEBUG)
