more golfed version based on the same idea:
def f(s): for a in s:print(*map('{:>4}'.format,[*a,*a.encode()]),end='\n\n') If there are '\t's in the input, then change the 4 to a 9.
Prior version:
def f(s): for l in s: print(*l,sep='\t',end='');print(*l.encode(),sep='\t',end='\n\n') Takes a list of strings, each ending with a '\n'.
