常用模块封装

• 日志收集器封装成类

# 日志收集器封装类
import logging # 导入logging模块

class MyLogger:
    def __init__(self, name):
        self.logger = logging.Logger(name)
        self.logger.setLevel('DEBUG')
        self.s = logging.StreamHandler()
        self.s.setLevel('DEBUG')
        self.f = logging.FileHandler('tools.log', encoding='utf-8')
        self.f.setLevel('DEBUG')
        self.logger.addHandler(self.s)
        self.logger.addHandler(self.f)
        ft = logging.Formatter("[%(asctime)s - line:%(lineno)d ]: %(levelname)s: %(message)s")
        self.s.setFormatter(ft)
        self.f.setFormatter(ft)

    def info(self, msg, *args, **kwargs):
        self.logger.info(msg, *args, **kwargs)

    def debug(self, msg, *args, **kwargs):
        self.logger.debug(msg, *args, **kwargs)

    def warning(self, msg, *args, **kwargs):
        self.logger.warning(msg, *args, **kwargs)

    def error(self, msg, *args, **kwargs):
        self.logger.error(msg, *args, **kwargs)
