How to log source file name and line number in Python

Question

Is it possible to decorate/extend the python standard logging system, so that when a logging method is invoked it also logs the file and the line number where it was invoked

Answer 1

# your imports above ...


logging.basicConfig(
    format='%(asctime)s,%(msecs)d %(levelname)-8s [%(pathname)s:%(lineno)d in 
    function %(funcName)s] %(message)s',
    datefmt='%Y-%m-%d:%H:%M:%S',
    level=logging.DEBUG
)

logger = logging.getLogger(__name__)

# your classes and methods below ...
# An naive Sample of usage:
try:
    logger.info('Sample of info log')
    # your code here
except Exception as e:
    logger.error(e)

Different of the other answers, this will log full path of file and the function name that might have occurred an error. This is useful if you have a project with more than one module and several files with the same name distributed in these modules.
