How to get the last byte item from a bytes list in Python?

I have a bytes list and want to get the last item, while preserving its bytes type. Using [-1] it gives out an int type, so this is not a direct solution.

Example code:

x = b'\x41\x42\x43'  y = x[-1]  print (y, type(y))  # outputs:  67 <class 'int'>  

For an arbitrary index I know how to do it:

x = b'\x41\x42\x43'  i = 2 # assume here a valid index in reference to list length  y = x[i:i+1]  print (y, type(y))  # outputs:  b'C' <class 'bytes'>  

Probably I can calculate the list length and then point an absolute length-1 number, rather than relative to list end.

However, is there a more elegant way to do this ? (i.e. similar to the simple [-1]) I also cannot imagine how to adapt the [i:i+1] principle in reverse from list end.
