Field description:


[Loggers]
# Define the logger module. root is the parent class and must exist. Others are custom.
# Logging. getLogger (NAME) is equivalent to registering a log print with the logging Module
# Use. In name to indicate the inheritance relationship of log

[Handlers]
# Define handler

[Formatters]
# Define the formatting output [logger_root]

# The Implementation of the logger module defined above must be in the form of [logger_xxxx]

# [Logger_xxxx] logger _ Module name
# Level: DEBUG, INFO, WARNING, ERROR, and CRITICAL
# Handlers processing classes, which can be separated by commas
# Qualname: logger name, which is obtained by the application through logging. getLogger. For names that cannot be obtained, record them to the root module.
# Whether propagate inherits the log information of the parent class, 0: No 1: Yes

[Handler_infohandler]
# [Handler_xxxx]
# Class handler class Name
# Level Log level
# Formatter, The formatter defined above
# Args handler initialize function parameters
[Formatter_form01]

# Log format
#--------------------------------------------------
# % (Asctime) s year-month-day hour-minute-second, millisecond 20:10:43, 745
# % (Filename) s file name, excluding Directories

# % (FuncName) s function name
# % (Levelname) s-level name

logger=logging.getLogger('infoLogger')
logger.info('test1')
logger_error=logging.getLogger('errorhandler')
logger_error.error('test5')
