3.了解ConfigParser;
ini配置文件格式:
节:[session]
参数(键=值)
[port]
port1=3306
import ConfigParser
cfg=ConfigParser.ConfigParser()
vim test.txt
[userinfo]
name=nyan
pwd=password
[study]
python_base=15
python_junior=30
linux_base=15
cfg.read(‘test.txt‘)
cfg.sections()
cfg.items
for se in cfg.sections():
print se
print cfg.items(se)
cfg.set(‘userinfo‘,‘pwd‘,‘passw0rd‘):修改
cfg.set(‘userinfo‘,‘email‘,‘sibaoemail@qq.com‘):插入
cfg.remove_option(‘userinfo‘,‘email‘)

1.dump ini
2.del section
3.del item
4.modify item
5.add section
6.save modify
