python 内置模块之ConfigParser--配置读写

用于对特定的配置进行操作，当前模块的名称在 python 3.x 版本中变更为 configparser。

#配置文件test.cfg
[section1]
k1 = v1
k2 :v2
k3 = 1

[section2]
k1 = v1

#coding:utf-8
import ConfigParser

config = ConfigParser.ConfigParser()
config.read('test.cfg')

# ########## 读 ##########
#获取所有sections.
secs = config.sections()
print secs  #['section1', 'section2']

#获取制定section的键key
options = config.options('section1')
print options   #['k1', 'k2', 'k3']
#获取指定section的键值对key-value
item_list = config.items('section1')
print item_list #[('k1', 'v1'), ('k2', 'v2'), ('k3', '1')]

#获取指定key的value
# 获取字符串类型的value
val1 = config.get('section1','k1')
# 获取整型的value
val2 = config.getint('section1','k3')

# ########## 增改删 ##########
# 增加section
if not config.has_section('section3'):
    config.add_section('section3')
    config.write(open('test.cfg', "w"))

#设置option
if not config.has_section('section3'):
    config.set('section3','k1',11111)
    config.write(open('test.cfg', "w"))

# 移除option
ret = config.remove_option('section3','k1')
print ret   #True or False
config.write(open('test.cfg', "w"))
# 移除section
ret = config.remove_section('section3')
print ret   #True or False
config.write(open('test.cfg', "w"))
