Python内置模块ConfigParser实现配置读写功能的方法

#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"))
