To log an exception in Python we can use logging module and through that we can log the error.
Logging module provides a set of functions for simple logging and for following purposes
- DEBUG
- INFO
- WARNING
- ERROR
- CRITICAL
Logging an exception in python with an error can be done in the logging.exception()
method. This function logs a message with level ERROR on this logger. The arguments are interpreted as for debug()
. Exception info is added to the logging message. This method should only be called from an exception handler.
See the following code for more clearity:
Example 1 :
# importing the module import logging try : printf( "GeeksforGeeks" ) except Exception as Argument: logging.exception( "Error occured while printing GeeksforGeeks" ) |
Output :
ERROR:root:Error occured while printing GeeksforGeeks Traceback (most recent call last): File "/home/gfg.py", line 3, in printf("GeeksforGeeks") NameError: name 'printf' is not defined
Example 2 : We can also log the error message into different file without showing error in the console by the following method:
# importing the module import logging try : printf( "GeeksforGeeks" ) except Exception as Argument: # creating/opening a file f = open ( "demofile2.txt" , "a" ) # writing in the file f.write( str (Argument)) # closing the file f.close() |
Error message will be stored in file name demofille2.txt in same directory as code.
Output :
Traceback (most recent call last): File "/home/gfg.py", line 5, in printf("GeeksforGeeks") NameError: name 'printf' is not defined
