Python-configparser Common Operations Example __python

Configparser module is used to manipulate configuration files
The configuration file format is similar to the Windows INI file, and can contain one or more sections (section), and each section can contain multiple parameters (key-value pairs form: key=value) Configparser Common methods

1, Config=configparser.configparser ()  
Create Configparser instance  

2, config.sections ()  --> list
Returns the sequence 3, config.options (section)--> List of all the sections in the configuration file  returns the
sequence  

4, Config.get (section,option) of all keys in a project  --> str
returns a section, option's key value  

5, config.add_section (str)  
adds a profile section (str)  

6, Config.set (Section,option,val)  
Sets the value of the key to option (Val)  

7, config.read (filename) to  
read configuration file  

8, Config.write (obj_file)  
Write configuration file

Execution Results

Sections: [' section_1 ', ' section_2 ']
[section_1]
    key_1=value_1_1
    key_2=value_1_2
[section_2]
    key_1=value_2_1
    key_2=value_2_2
    key_3=value_2_3
Modified:
sections: [' Section_ 1 ', ' section_2 ']
[section_1]
    key_1=value_1_1
    key_2=value_1_2
    key_3=value_1_3
[section_ 2]
    key_1=value_2_1
    key_2= modified the
    key_3=value_2_3
end
