python的logging模块(logging是线程安全的)给应用程序提供了标准的日志信息输出接口。logging不仅支持把日志输出到文件,还支持把日志输出到TCP/UDP服务器,EMAIL服务器,HTTP服务器,UNIX的syslog系统等。在logging中主要有四个概念:logger、handler、filter和formatter,下面会分别介绍。logger Logger对象扮演了三重角色: 它给...

比如：http://www.weather.com.cn/data/cityinfo/101021200.html 上海徐汇区对应的天气网址。具体代码如下：mport requests import json import logging as log defget_weather_wind(url): r = requests.get(url) if r.status_code != 200: log.error("Can't get weather data!") info = json....
The benefits of logging Basic logging Advanced configuration to logging An example of the use of loggingBenefits of LoggingYou may ask: “Why not just use printing?”When you run an algorithm and want to confirm it is doing what you expected, it is natural to add some print() statements ...
Python logging, on the other hand, comes pre-built with such options and features that make printing completely inefficient. print()statements require access to the console. In addition, print messages are momentary; as soon as you close the program, the output will be erased. But, Python log...
Note that the order in which the inner functions are defined does not matter. Like with any other functions, the printing only happens when the inner functions are executed.Furthermore, the inner functions aren’t defined until the parent function is called. They’re locally scoped to parent(...
Print Logs in Python - Logging ModuleIn this tutorial, we will learn what is logging? (basics of logging), how we can print logs in python and the different log levels that should be used while printing logs.First of all, let us discuss what is logging.What is Logging?
logging模块 re正则表达式 模块,使用代码实现了某个功能的代码集合。 类似于函数式编程和面向过程编程,函数式编程则完成一个功能,其他代码用来调用即可,提供了代码的重用性和代码间的耦合。而对于一个复杂的功能来,可能需要多个函数才能完成(函数又可以在不同的.py文件中),n个 .py 文件组成的代码集合就称为模块。
