python模块--config

一、创建文件

##-----------------创建数据表--------------------------
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['Host Post'] = '50022'  #mutates the parser
topsecret['ForwardX11'] = 'no' #same here

with open('example.ini','w') as f:
    config.write(f)

2、增删改查--查

###----------增删改查------------------------------
import configparser
config = configparser.ConfigParser()


print(config.sections())  # 返回空列表[]
# print(config.user())
##------------> 查
config.read('example.ini')
print(config.sections())  #['bitbucket', 'topsecret.server.com']

print('bytebong.com' in config)   #False
print(config['bitbucket.org']['user'])   # hg

print(config['topsecret.server.com']['host post'])   #50022
print(config['topsecret.server.com']['forwardx11'])  #no
print(config['DEFAULT']['serveraliveinterval'])   #45

for key in config['bitbucket.org']:
    print('【bit】',key)

print(config.options('bitbucket.org'))  # ??['user', 'serveraliveinterval', 'compression', 'compressionlevel']
print(config.items('bitbucket.org'))  #[('serveraliveinterval', '45'), ('compression', 'yes'), ('compressionlevel', '9'), ('user', 'hg')]
##  下面的两组，不管取哪个，都会把[DEFAULT] 里面的顺带打印出来，这以后在实际中有相应的应用、

print(config.get('bitbucket.org','compression'))   #?? yes

3、增、改、删

##------> 删、改、增
config.add_section('zhao')   #  增加一条
config.set('zhao','key','python')

config.remove_section('topsecret.server.com')
config.remove_option('bitbucket.org','user')

config.write(open('zhao',"w"))
