Python基礎-ConfigParser模塊
阿新 • • 發佈:2018-03-02
ng- def section 一個 user 解析 false group onf
此模塊用於生成和修改常見配置文檔,當前模塊的名稱在 python 3.x 版本中變更為 configparser。
來看一個好多軟件的常見配置文件格式如下
[DEFAULT]
ServerAliveInterval = 45
Compression = yes
CompressionLevel = 9
ForwardX11 = yes
[bitbucket.org]
User = hg
[topsecret.server.com]
Port = 50022
ForwardX11 = no
解析配置文件
>>> import configparser
>>> config = configparser.ConfigParser()
>>> config.sections()
[]
>>> config.read(‘example.ini‘)
[‘example.ini‘]
>>> config.sections()
[‘bitbucket.org‘, ‘topsecret.server.com‘]
>>> ‘bitbucket.org‘ in config
True
>>> ‘bytebong.com‘ in config
False
>>> config[‘bitbucket.org‘][‘User‘]
‘hg‘
>>> config[‘DEFAULT‘][‘Compression‘]
‘yes‘
>>> topsecret = config[‘topsecret.server.com‘]
>>> topsecret[‘ForwardX11‘]
‘no‘
>>> topsecret[‘Port‘]
‘50022‘
>>> for key in config[‘bitbucket.org‘]: print(key)
...
user
compressionlevel
serveraliveinterval
compression
forwardx11
>>> config[‘bitbucket.org‘][‘ForwardX11‘]
‘yes‘
其它增刪改查語法
[group1] k1 = v1 k2:v2 [group2] k1 = v1 import ConfigParser config = ConfigParser.ConfigParser() config.read(‘i.cfg‘) # ########## 讀 ########## #secs = config.sections() #print secs #options = config.options(‘group2‘) #print options #item_list = config.items(‘group2‘) #print item_list #val = config.get(‘group1‘,‘key‘) #val = config.getint(‘group1‘,‘key‘)
# ########## 改寫 ##########
import configparser
config = configparser.ConfigParser()
config.read(‘test.ini‘)
# sec = config.remove_section(‘group1‘)
# config.write(open(‘i.cfg‘, ‘w‘))
# sec = config.has_section(‘wupeiqi‘)
# print(sec)
# sec = config.add_section(‘wupeiqi‘)
# config.write(open(‘i.cfg‘, ‘w‘))
# config.set(‘group2‘, ‘k1‘, ‘111111‘)
# config.write(open(‘i.cfg‘, ‘w‘))
config.remove_option(‘group2‘, ‘k3‘)
config.write(open(‘i.cfg‘, ‘w‘))
