configpraser模块

configpraser配置文件，example.conf

[data] #节点
username = Jason
password = 123

[public]
comment = stuff
public = True
pi = 3.1415926
test_int = 9

程序实例

import configparser
config = configparser.ConfigParser()
config.read("example.conf", "utf-8")
ret = config.sections() #获取所有的节点
print(ret) #['data', 'public']
print(config.items('data'))#获取指定节点下的所有键值对
#[('username', 'Jason'), ('password', '123')]
print(config.options("public")) #获取指定节点下的所有键
#['comment', 'public', 'pi']
print(config.get('data', 'username')) #获取指定节点下指定key的值
#Jason
res1 = config.getint('public','test_int')#获取指定节点下key值，必须为整数否则报错
res2 = config.getfloat('public','pi')#获取指定节点下key值，必须为浮点数否则报错
res3 = config.getboolean('public','public')#获取指定节点下key值，必须为布尔值否则报错
print(res1, res2, res3)
check = config.has_section("data") #检查节点
print(check)
#True

添加节点

config.add_section('local') #添加节点
config.write(open('example.conf','w')) #
ret = config.sections()
print(ret)
#['global', 'public', 'local']

删除节点

config.remove_section('local') #删除节点
config.write(open('example.conf','w'))#重新写入文件
ret = config.sections()
print(ret)
#['global', 'public']

检查，删除，设置指定组内的键值对

#检查
check = config.has_option('public','comment')#检查节点下的某个键，返回布尔值
print(check)
输出:
True

#删除
config.remove_option('global','workgroup')
config.write(open('example.txt','w'))
ret = config.options('global')
print(ret)
#输出：
['security', 'maxlog']


#设置指定节点内的键值对
ret1 = config.get('global','maxlog')
print(ret1)
config.set('global','maxlog','100')
config.write(open('example.txt','w'))
ret2 = config.get('global','maxlog')
print(ret2)

#输出：
50
100

configpraser设置多个配置文件然后遍历，这样做Frabic作业分组问题简直超级方便，but遇到了问题！！！

#!/usr/bin/env python

import os
import sys
import configparser

BASE_DIR = os.path.dirname(os.path.abspath(__file__))
sys.path.append(BASE_DIR)
db_path = os.path.join(BASE_DIR, "db")
config_info = configparser.ConfigParser()
group_dic = {}
group_list = os.listdir(db_path)
print(group_list)
for group in group_list:
    group_path = os.path.join(db_path, str(group))
    config_info.read(group_path, "utf-8")
    ip_list = config_info.sections()
    print("ip list>>", ip_list)
    group_dic.update({group: ip_list})
    print(group)
    print("group dict", group_dic)

输出结果

['111', '33']
ip list>> ['192.168.1.1']
111
group dict {'111': ['192.168.1.1']}
ip list>> ['192.168.1.1', '192.168.229.128', '192.168.229.131']
33
group dict {'111': ['192.168.1.1'], '33': ['192.168.1.1', '192.168.229.128', '192.168.229.131']}

两个配置文件
33

[192.168.229.128]
user = jason
pwd = 123
ports = 22

[192.168.229.131]
user = jason
pwd = 123
ports = 33

111

[192.168.1.1]
user = dog
pwd = 123
ports = 88

补充：
在config.read("file_path"),前加config.clear()即可解决上述问题
