Linux under many configuration files in addition to the INI format can be used in Python configparser module, you can write a simple code of their own only "key=value" such a conf configuration file to parse into a dictionary, The key corresponding to key can be easily obtained by using the dictionary keys.

Example of how to parse a json file in python, Preface JSON (JavaScript Object Notation) is a lightweight data exchange format. It is based on a subset of JavaScript (Standard ECMA-262 3rd Edition-December 1999.

The INI file is a frequently used configuration file in Windows, and the main format is: Copy Code code as follows: [Section1] Option1:value1 Option2:value2 Python provides a simple module configparser can be used to parse files similar to this form. For the Configparser module, you can

This article mainly introduces the code for parsing the crontab configuration file implemented by python. It can also be called the crontab of python. the code contains a large number of comments. For more information, see #/Usr/bin/env python #-*-coding: UTF-8-*-"" 1. parse

Because the company's internal interface returns the string support 2 kinds of forms: PHP array, XML; results php array python can not be used directly, and XML string format is not standard, so also can not use the standard module parsing. "Non-standard place is the name of some node will be the beginning of the number", so write a simple step to parse the file,

Python's most recent work is the component compatibility test, the original framework has a lot of features are not perfect, need to add! For example, you need to write the results of the AutoIt script to Excel, and the final solution is to use the local log to parse the result! The following class is added to complete the above functions: Copy Code code as follows: Class Autoitresultparser ()
