Python how to get only the last 2 bytes of the reply data

Question

I will post a query to a device which will return me with something like this (after a readlines):

['\x03C?01FF00\r']

I want to extract just the FF00 and post the reply to the jquery (which sends the query) and display it out on browser. How can i do that? The 2 bytes range from 0000 to FFFF.

EDIT: the reply type is list .

Answer 1

假设ans = ['\\x03C?01FF00\\r'] ，则ans[0].strip()[-4:]应产生'FF00'
