• -sections ()                         get all the sections and return as a list
• -options (section)              Get all option
• -items (section)    for the section;                gets all the key values for the section to

2. Basic write operation

• -write (FP) writes the Config object to a. init format file , write a. Ini-format representation of the configuration state.
• -add_section (section) Add a new section
