Question

我是第一次使用日志记录模块。我能够按照我的要求编写程序。 try和except内部编写的逻辑也几乎可以成功运行，并且在日志文件中生成了日志。但是由于某种原因，我在IDE控制台上看到所有“ logging.info”和“ logging.exception”的“ AttributeError”。因此，为了进行交叉验证，我注释掉了所有这些位置，这一次我的代码运行无任何错误，但日志文件中未记录任何内容。这很明显。下面是整个程序

import logging
from logging.handlers import TimedRotatingFileHandler

logger = logging.handlers.TimedRotatingFileHandler('amitesh.log', when='midnight', interval=1)
logger.suffix = '%y_%m_%d.log'
# create a logging format
LOGGING_MSG_FORMAT = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
logger.setFormatter(LOGGING_MSG_FORMAT)

LOGGING_DATE_FORMAT = '%d-%b-%y %H:%M:%S'

# create basic configuration
logging.basicConfig(level=logging.INFO, format=LOGGING_MSG_FORMAT, datefmt=LOGGING_DATE_FORMAT)


root_logger = logging.getLogger('')


# add the handlers to the logger
root_logger.addHandler(logger)
while True:
    print(" ")
    print("This is a Logging demo")
    print(" ")
    logging.info("new request came")
    print(" ")
    try:
        x = int(input("Enter the first number: "))
        y = int(input("Enter the second number: "))
        print(x / y)
    except ZeroDivisionError as msg:
        print("cannot divide with zero")
        logging.exception(msg)
        print(" ")
    except ValueError as msg:
        print("enter only integer value")
        logging.exception(msg)
        print(" ")
    logging.info("executed successfully")

print(" ")

以下是我的IDE控制台中的错误消息：

    return self._fmt.find(self.asctime_search) >= 0
AttributeError: 'Formatter' object has no attribute 'find'
Call stack:
  File "/Users/amitesh/PycharmProjects/Automation/Databases/DB_Conn.py", line 68, in <module>
    logging.info("new request came")
Message: 'new request came'
Arguments: ()

过去2天，我没有任何运气就上网了。请帮助我找出我的错误。

添加了更多错误：

  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/logging/__init__.py", line 388, in usesTime
    return self._fmt.find(self.asctime_search) >= 0

谢谢。

删除了format = LOGGING_MSG_FORMAT，LOGGING_MSG_FORMAT，并直接使用“ format”参数定义了basicConfig内部的值，因为参数“ format”采用字符串而不是Formatter类型。

为什么Python日志记录模块抛出Attribute错误？
