# import required libraries from PyQt.QtCore import QSettings # create a QSettings object settings = QSettings('MyOrganization', 'MyApp') # set some values under a parent group settings.setValue('preferences/font_size', 12) settings.setValue('preferences/font_family', 'Arial') settings.setValue('preferences/color_scheme/font_color', 'red') settings.setValue('preferences/color_scheme/background_color', 'white') # retrieve all child group keys under the parent group 'preferences' child_groups = settings.childGroups('preferences') # print the list of child group keys print(child_groups)In this example, we create a QSettings object with the organization and application names, set some values under a parent group, and then retrieve all the child group keys under the 'preferences' parent group. The output should be a list of one string: ['color_scheme']. From the code examples, it is determined that the package library used is PyQt.QtCore.
