Get frame type from xbee message in python

I use python library developed for XBee module. In communication, when a message received by the module and transfer to uC, by function “read_data” in XBeeDevice class,the message can be fetch, and by functions in XBeeMessage Class, some parts of the packet (data, address of the source, …) can be extracted form the main message, but it is limited and all parts of it were not included as function in XBeeMessage class. I need to fetch “frame type” of the message, but I don not know how to get it.
