This is most likely a bash prompt. Therefore "od" is a program on your
computer.  Nothing to do with Python at all.

To get Python to display \x## hex codes for non-ascii characters in a
byte stream, you can print out the repr() of the byte string.  For example:

print (repr(my_unicode_string.encode('utf-8')))
