此模組用於生成和修改常見配置文件，當前模組的名稱在 python 3.x 版本中變更為 configparser。

解析下面的檔案格式：

[DEFAULT]
ServerAliveInterval = 45   
Compression = yes
CompressionLevel = 9
ForwardX11 = yes

[bitbucket.org]
User = hg

[topsecret.server.com]
Port = 50022
ForwardX11 = no

解析配置檔案

import configparser

conf = configparser.ConfigParser()  #
 
 例項化(生成物件)

# print(conf.sections()) #呼叫sections方法  []

conf.read('conf.ini')  # 讀配置檔案(注意檔案路徑)

print(conf.sections())  # 呼叫sections方法(預設不會讀取default  #['bitbucket.org', 'topsecret.server.com']
print(conf.default_section)  # ['bitbucket.org', 'topsecret.server.com']

# print(conf['bitbucket.org']['User']) # hg
 


for key, value in conf['bitbucket.org'].items():
    print(key, value)  # 每個節點會有預設有DEFAULT的引數
'''
user hg
serveraliveinterval 45
compression yes
compressionlevel 9
forwardx11 yes
'''

if 'user' in conf['bitbucket.org']:
    print('True')

# 查

conf = configparser.ConfigParser()

conf.read(
 
'conf2.ini')
#
print(conf.options('group1'))  # 拿到key
print(conf['group1']['k2'])  # v2 拿到value

print(conf.has_option('group1', 'key1'))  # False

# 增

conf.add_section('group3')
conf['group3']['name'] = 'Alex Li'
conf['group3']['age'] = '22'
conf.write(open('conf3.ini', 'w'))

'''
[group1]
k1 = v1
k2 = v2

[group2]
k1 = v1

[group3]
name = Alex Li
age = 22
'''

# 刪


conf.remove_option('group1', 'k2')
conf.remove_section('group1')  # 把整個group1和裡面的內容全刪了
conf.write(open('conf4.ini', 'w'))

# 改

conf['group1']['k1'] = 'haha'
conf.write(open('conf2.ini', 'w'))
