The process to find the bug

The process of recording a program on a business trip yesterday I find a bug

Yesterday was the program

    while True:

        print(38 * '-')
        user_shopping_chiose = input('请输入你要选择的功能')
        if user_shopping_chiose not in msg_dict:
            print('请好好输入')
            continue
        elif user_shopping_chiose=='q':
            print('再见')
            logger_end('程序主界面')
            break
        else:
            logger_start(f'{app_name_dict[user_shopping_chiose]}')
            msg_dict[user_shopping_chiose]()
            logger_end(f'{app_name_dict[user_shopping_chiose]}')

I will place in which to print the log of problems running, commented elsewhere

if __name__ == '__main__':
    #logger_start('程序主界面')
    while True:
        print("\033[0;31;44m\t\t杨大爷超市欢迎您\t\t\t\t\033[5m")
        print("\033[0;30;42m\t\t输入0进入注册界面\t\t\t\033[5m")
        print("\033[0;30;42m\t\t输入1进入登入界面\t\t\t\033[5m")
        print("\033[0;30;42m\t\t输入2进入充值界面\t\t\t\033[5m")
        print("\033[0;30;42m\t\t输入3进入余额查询界面\t\t\033[5m")
        print("\033[0;30;42m\t\t输入4进入购物界面\t\t\t\033[5m")
        print("\033[0;30;42m\t\t输入5进入解冻界面\t\t\t\033[5m")
        print("\033[0;30;42m\t\t输入q退出程序 \t\t\t\t\033[5m")
        print(38 * '-')
        user_shopping_chiose = input('请输入你要选择的功能')
        if user_shopping_chiose not in msg_dict:
            print('请好好输入')
            continue
        elif user_shopping_chiose=='q':
            print('再见')
            logger_end('程序主界面')
            break
        else:
            logger_start(f'{app_name_dict[user_shopping_chiose]}')
            msg_dict[user_shopping_chiose]()
            #logger_end(f'{app_name_dict[user_shopping_chiose]}')

The resulting log

We found the inside of the log-correlation function should also exist after he runs, this time we take a look at the original function

logger.py

def logger_start(app):
    logger_login = logging.getLogger('start')
    fli_show = logging.FileHandler('app.log')
    logger_format = logging.Formatter('%(message)s程序启动时间:%(asctime)s',
                     datefmt='%Y-%m-%d %X' )
    fli_show.setFormatter(logger_format)
    logger_login.addHandler(fli_show)
    logger_login.setLevel(10)
    logger_login.info(app)
    
#这时候我又三种想法,
#第一种把函数return出来,每次赋予不同的变量名,这里可以用时间生成函数来进行保证每次函数名不一样
#第二种找可能会出现相同地方'logger_login'这个名字
#第三种找可能会出现相同地方logging.getLogger('start')中('start')这个名字

I chose the easiest to modify the third modified

import logging
from data_time import data_time
def logger_login(user):
    logger_login = logging.getLogger(data_time()) #这是我自定义的一个函数返回值是当前时间每次都会不同
    fli_show = logging.FileHandler('user_login.log')
    logger_format = logging.Formatter('登入时间:%(asctime)s  %(levelname)s-用户:%(message)s',
                     datefmt='%Y-%m-%d %X' )
    fli_show.setFormatter(logger_format)
    logger_login.addHandler(fli_show)
    logger_login.setLevel(10)
    logger_login.info(user)


def logger_exit(user):
    logger_login = logging.getLogger(data_time())
    fli_show = logging.FileHandler('user_login.log')
    logger_format = logging.Formatter('退出时间:%(asctime)s  %(levelname)s-用户:%(message)s',
                     datefmt='%Y-%m-%d %X' )
    fli_show.setFormatter(logger_format)
    logger_login.addHandler(fli_show)
    logger_login.setLevel(10)
    logger_login.info(user)

def logger_start(app):
    logger_login = logging.getLogger(data_time())
    fli_show = logging.FileHandler('app.log')
    logger_format = logging.Formatter('%(message)s程序启动时间:%(asctime)s',
                     datefmt='%Y-%m-%d %X' )
    fli_show.setFormatter(logger_format)
    logger_login.addHandler(fli_show)
    logger_login.setLevel(10)
    logger_login.info(app)
    

def logger_end(app):
    logger_login = logging.getLogger(data_time())
    fli_show = logging.FileHandler('app.log')
    logger_format = logging.Formatter('%(message)s程序关闭时间:%(asctime)s',
                     datefmt='%Y-%m-%d %X' )
    fli_show.setFormatter(logger_format)
    logger_login.addHandler(fli_show)
    logger_login.setLevel(10)
    logger_login.info(app)

def logger_shopping(user,car):
    logger_login = logging.getLogger(data_time())
    fli_show = logging.FileHandler('user_shopping.log')
    logger_format = logging.Formatter('%(asctime)s  %(levelname)s-%(message)s',
                     datefmt='%Y-%m-%d %X' )
    fli_show.setFormatter(logger_format)
    logger_login.addHandler(fli_show)
    logger_login.setLevel(10)
    logger_login.info(user,car)

Finally it solved
