Python 中使用 configparser 模块来操作 ini 文件。
假如想要生成 example.ini 文件，内容如下：
1
2
3
4
5
6
7
8
9
10
11
| ServerAliveInterval = 45
Compression = yes
CompressionLevel = 9
ForwardX11 = yes
[bitbucket.org]
User = hg
[topsecret.server.com]
Port = 50022
ForwardX11 = no
|
写入操作
configparser.ConfigParser() 方法生成实例，配置和读取内容都可以按照 dict 的方式进行。

| >>> import configparser
>>> config = configparser.ConfigParser()
>>> config['DEFAULT'] = {'ServerAliveInterval': '45',
... 'Compression': 'yes',
... 'CompressionLevel': '9'}
>>> config['bitbucket.org'] = {}
>>> config['bitbucket.org']['User'] = 'hg'
>>> config['topsecret.server.com'] = {}
>>> topsecret = config['topsecret.server.com']
>>> topsecret['Port'] = '50022' # mutates the parser
>>> topsecret['ForwardX11'] = 'no' # same here
>>> config['DEFAULT']['ForwardX11'] = 'yes'
>>> with open('example.ini', 'w') as configfile:
... config.write(configfile)

修改操作
因为此处配置的写入是覆盖模式，所以如果想要修改文件，需要判断下文件是否存在，存在的话，先加载文件内容。

| def config(filepath, section, **data):

if os.path.exists(filepath):
conf.read(filepath)
conf[section] = data
with open(filepath, 'w') as f:
conf.write(f)
f.close()
