  • import gi
gi.require_version("Gtk", "3.0")
from gi.repository import Gtk as gtk

settings = gtk.Settings.get_default()
settings.set_property("gtk-theme-name", "Numix")
settings.set_property("gtk-application-prefer-dark-theme", False)  # if you want use dark theme, set second arg to True

# getting all existing properties #

for i in settings.list_properties():
    print(i)
