f_str = logging.Formatter("%(asctime)s %(name)s %(levelname) %(filenname)s %(lineno)s %(message)s")
Set a record level
looger.level = 10
fh.setFormatter (f_str) # handle to the file format of the recorded contents provided
fh.setFormatter (f_str) # console to format the content provided
looger objects looger.addHandler (fh) # add the file handle in
looger.addHandler (ch ) # looger objects will be added in the center console
looger.debug (1234) # We secondary development
looger.info (1234) # We secondary development
