try except - when exception occure write it in file using python -

i wants write exception details in file: tried below"

def writeerrorlog(e) :    global lcnt     lsterr=[]     iurlfoutputfile = open("c:\error.log", "a")    csvurlfinfowriter = csv.writer(iurlfoutputfile,  delimiter=',', lineterminator='\n')    exc_type, exc_obj, exc_tb = sys.exc_info()    fname = os.path.split(exc_tb.tb_frame.f_code.co_filename)[1]    csvurlfinfowriter.writerow('[exc_type, filename, script_line no,inputfile_lineno]')    lsterr.append(exc_type)    lsterr.append(fname)    lsterr.append(g_lcnt)    value in lsterr :        csvurlfinfowriter.writerow(value)     iurlfoutputfile.close() 

in except block:

 except exception e :         writeerrorlog(e) 

its not working, can correct me? or can suggest better option? thanks!!

i use python loggin -> http://docs.python.org/2/library/logging.html can format lines ',' delimited, example

[formatter_generic_form] format='%(asctime)s , %(levelname)s , %(message)s' datefmt='%y-%m-%d %h:%m:%s' 

datetime, level_of_log, whatever_message_you_want_to_log

i recommend http://docs.python.org/2/howto/logging.html#logging-basic-tutorial start
