配置文件--configparser

Posted 2020-10-22 清欢

import configparser
config = configparser.ConfigParser()
config["DEFAULT"] = {\'ServerAliveInterval\': \'45\',
                      \'Compression\': \'yes\',
                     \'CompressionLevel\': \'9\',
                     \'ForwardX11\':\'yes\'
                     }
config[\'bitbucket.org\'] = {\'User\':\'hg\'}
config[\'topsecret.server.com\'] = {\'Host Port\':\'50022\',\'ForwardX11\':\'no\'}
with open(\'example.ini\', \'w\') as f:
   config.write(f)

 

生成example.ini文件

 

import configparser
config = configparser.ConfigParser()
#---------------------------查找文件内容,基于字典的形式
print(config.sections())        #  []
config.read(\'example.ini\')
print(config.sections())        #   [\'bitbucket.org\', \'topsecret.server.com\']

print(\'bytebong.com\' in config) # False
print(\'bitbucket.org\' in config) # True

print(config[\'bitbucket.org\']["user"])  # hg
print(config[\'DEFAULT\'][\'Compression\']) #yes
print(config[\'topsecret.server.com\'][\'ForwardX11\'])  #no
print(config[\'bitbucket.org\'])          #<Section: bitbucket.org>
for key in config[\'bitbucket.org\']:     # 注意,有default会默认default的键
    print(key)
print(config.options(\'bitbucket.org\'))  # 同for循环,找到\'bitbucket.org\'下所有键
print(config.items(\'bitbucket.org\'))    #找到\'bitbucket.org\'下所有键值对 元组形式
print(config.get(\'bitbucket.org\',\'compression\')) # yes       get方法Section下的key对应的value

文件基本操作

 1 import configparser
 2 config = configparser.ConfigParser()
 3 config.read(\'example.ini\')   # 读文件
 4 config.add_section(\'yuan\')   # 增加section
 5 config.remove_section(\'bitbucket.org\')   # 删除一个section
 6 config.remove_option(\'topsecret.server.com\',"forwardx11")  # 删除一个配置项
 7 config.set(\'topsecret.server.com\',\'k1\',\'11111\')
 8 config.set(\'yuan\',\'k2\',\'22222\')
 9 f = open(\'new2.ini\', "w")
10 config.write(f) # 写进文件
11 f.close()
