本文实例讲述了Python读写配置文件的方法。分享给大家供大家参考。具体分析如下:

python 读写配置文件在实际应用中具有十分强大的功能,在实际的操作中也有相当简捷的操作方案,以下的文章就是对python 读写配置文件的具体方案的介绍,相信对大家学习Python有所帮助。

python 读写配置文件ConfigParser模块是python自带的读取配置文件的模块.通过他可以方便的读取配置文件. 这里就来简单介绍一下python 读写配置文件的方法.
配置文件.顾名思议就是存放配置信息的文件.下面是个例子

[info] 
age = 21
name = chen
gender = male

其中[ ] 中的info是这段配置的名字下面age,name都是属性下面的代码演示了如何读取python 读写配置文件.和修改配置中变量的值

from __future__ import with_statement 
import ConfigParser 
config=ConfigParser.ConfigParser() 
with open(''testcfg.cfg'',''rw'') as cfgfile: 
config.readfp(cfgfile) 
name=config.get(''info'',''name'') 
age=config.get(''info'',''age'') 
print name 
print age 
config.set(''info'',''gender'',''male'') 
config.set(''info'',''age'',''21'') 
age=config.get(''info'',''age'') 
print name 
print age

首先

代码如下:

config=ConfigParser.ConfigParser()

得到一个配置config对象.下面打开一个配置文件 cfgfile. 用readfp()读取这个文件.这样配置的内容就读到config对象里面了.接下来一个问题是如何读取值.常用的方法是get() 和getint() . get()返回文本. getint()返回整数

代码如下:

name=config.get(''info'',''name'')

意思就是.读取config中info段中的name变量值.最后讲讲如何设置值.使用set(段名,变量名,值) 来设置变量.config.set(''info'',''age'',''21'') 表示把info段中age变量设置为21. 就这么简单. 以上就是对python 读写配置文件的相关介绍。

希望本文所述对大家的Python程序设计有所帮助。

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
