XkbLookupKeySym is the equivalent of the core XLookupKeySym function. For the core keyboard, given a keycode key and an Xkb state state, XkbLookupKeySym returns the symbol associated with the key in sym_rtrn and the list of modifiers that should still be applied in mods_rtrn. The state parameter is the state from a KeyPress or KeyRelease event. XkbLookupKeySym returns True if it succeeds.
