我正在尝试用Python登录，下面是我的目录结构。

3 directories, 9 files
我的logging.conf文件如下：
[loggers]
keys=mainlogger, Employee.employee
[handlers]
keys=employeeHandler, rootHandler
[formatters]
keys=employee_formatter, root_formatter
[logger_mainlogger]
level=DEBUG
handlers=rootHandler
[logger_Employee.employee]
level=INFO
handlers=employeeHandler
propagate=0
[handler_employeeHandler]
class=FileHandler
level=INFO
formatter=employee_formatter
args=('employee.log',)
[handler_rootHandler]
class=StreamHandler
level=DEBUG
formatter=root_formatter
[formatter_employee_formatter]
format=%(asctime)s - %(name)s - %(levelname)s - %(message)s
[formatter_root_formatter]
format=%(name)s - %(levelname)s - %(message)s
我的Employee.employee类：
import logging
logger = logging.getLogger(__name__)
logger.propagate = False
handler = logging.FileHandler(filename='employee.log')
format = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
handler.setFormatter(format)
logger.addHandler(handler)
class Employee:
def __init__(self, firstname, lastname):
self.firstname = firstname
self.lastname = lastname
logger.info(f"Created new employee with {firstname} and {lastname}")
这是我的主要功能：
import logging
import logging.config
logging.config.fileConfig('logging.conf')
logger = logging.getLogger('mainlogger')
from employee import employee
def add(x, y):
return x + y
def multiply(x, y):
return x * y
if __name__ == '__main__':
x = 10
y = 20
logger.debug(f"The result of adding numbers {x} and {y} are {add(x, y)}")
logger.debug(f"The result of multiplying numbers {x} and {y} are {multiply(x, y)}")
employee.Employee("Subhayan", "Bhattacharya")
employee.Employee("Shaayan", "Bhattacharya")
当我运行start_logging.py文件时，出现了这个奇怪的错误。
Traceback (most recent call last):
File "start_logging.py", line 5, in <module>
logging.config.fileConfig('logging.conf')
File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/logging/config.py", line 80, in fileConfig
_install_loggers(cp, handlers, disable_existing_loggers)
File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/logging/config.py", line 189, in _install_loggers
llist.remove("root")
ValueError: list.remove(x): x not in list
有人可以告诉我这里出了什么问题吗？我不太了解Python日志记录。
