python之常用标准库-configparser

configparser主要用于生成和修改常见配置文档，所以常见的操作为读和写

1.写

定义参数变量，赋值

直接赋值法

conf['test_default']={'test_line1':'test_line1'}

通过增加section ，set赋值法
```
conf.add_section('test')
```

     conf.set('test','test_line1','test_line1')

通过增加section.option赋值法

　　conf.add_section('test1')
　　x=conf['test1']
　　x['test_line1']='test_line1'

通过空字典赋值法

　　conf['test2']={}
　　conf['test2']['test_line1']='test_line1'

 1 #!/usr/bin/python
 2 import configparser
 3 
 4 conf=configparser.ConfigParser()
 5 #新增,写入
 6 #方式一
 7 conf['test_default']={'test_line1':'test_line1',
 8                   'test_line2':'test_line2',
 9                   'test_line3':'test_line3',
10                   'test_line4':'test_line4'}
11 
12 #方式二，先新增一个section,再设置配置属性
13 conf.add_section('test')
14 conf.set('test','test_line1','test_line1')
15 conf.set('test','test_line2','test_line2')
16 conf.set('test','test_line3','test_line3')
17 conf.set('test','test_line4','test_line4')
18 
19 conf.add_section('test1')
20 x=conf['test1']
21 x['test_line1']='test_line1'
22 x['test_line2']='test_line2'
23 x['test_line3']='test_line3'
24 x['test_line4']='test_line4'
25 
26 
27 
28 conf['test2']={}
29 conf['test2']['test_line1']='test_line1'
30 conf['test2']['test_line2']='test_line2'
31 conf['test2']['test_line3']='test_line3'
32 conf['test2']['test_line4']='test_line4'

写入文件

将conf变量里面的值存入文件中，打开文件，执行写操作

 1 #!/usr/bin/python
 2 import configparser
 3 
 4 conf=configparser.ConfigParser()
 5 conf['test_default']={'test_line1':'test_line1',
 6                   'test_line2':'test_line2',
 7                   'test_line3':'test_line3',
 8                   'test_line4':'test_line4'}
 9 #写入
10 with open('conf_test','w',encoding='utf-8') as f:
11     conf.write(f)

2.读

从变量里面读

 1 #!/usr/bin/python
 2 import configparser
 3 
 4 conf=configparser.ConfigParser()
 5 
 6 print(conf.read('conf_test'))
 7 
 8 print(conf.sections())#读所有section
 9 print(conf.options('test'))
10 print('test5' in conf) #section是否存在
11 print(conf['test2']['test_line1'])#读取sectiontest2中port属性的值
12 print(conf.items('test2'))#将配置key-value读出，可以通过dict转为字典

从文件里面读

1 #!/usr/bin/python
2 import configparser
3 
4 conf=configparser.ConfigParser()
5 conf.read('conf_test')#从文件里面读

3.移除

1 #!/usr/bin/python
2 import configparser
3 
4 conf=configparser.ConfigParser()
5 print(conf.has_option(section='test',option='test_line1'))#是否有这个配置
6 conf.remove_option(section='test',option='test_line1')#删除这个属性配置
7 conf.remove_section('test')
