如何使用configparser对象获取配置文件路径

Question

The code below initiates the conf variable which is an instance of the Configuration class which inherits from ConfigParser . In its __init__ method it reads the config_file and stores its configuration context in a memory. How can I get a file path to this config_file having conf object?

import ConfigParser
import os 


class Configuration(ConfigParser.ConfigParser):
    def __init__(self, config_file):
        ConfigParser.ConfigParser.__init__(self) 
        self.read(config_file)

    def saveSettings(self):
        if not self.has_section('Section A'):
            self.add_section('Section A')
        self.set('Section A', 'Option 1', 'Value 1')

config_file = os.path.join(os.path.expanduser('~'),'config.ini' )
conf = Configuration(config_file)
conf.saveSettings()

Answer 1

Simply assign the information to the instance ( self ):

def __init__(self, config_path):
    ConfigParser.ConfigParser.__init__(self) 
    self.read(config_path)
    self.config_path = config_path # this is now an instance attribute

then you can access it with the object:

conf_path = os.path.join(os.path.expanduser('~'),'config.ini' )
conf = Configuration(conf_path)

print( conf.conf_path ) # access via object
