If the data is in an UTF-8 compatible format, you can convert the bytes to a string.

>>> import curses
>>> print(str(curses.version, "utf-8"))
2.2

Optionally convert to hex first, if the data is not already UTF-8 compatible. E.g. when the data are actual raw bytes.

from binascii import hexlify
from codecs import encode  # alternative
>>> print(hexlify(b"\x13\x37"))
b'1337'
>>> print(str(hexlify(b"\x13\x37"), "utf-8"))
1337
>>>> print(str(encode(b"\x13\x37", "hex"), "utf-8"))
1337

If we take a look at the source for bytes   repr    it looks as if the b   is baked into the method   The most obvious workaround is to manually slice off the b   from the resulting repr      gt  gt  gt  x   b  x01 x02 x03 x04    gt  gt  gt  print repr x   b  x01 x02 x03 x04    gt  gt  gt  print repr x  2 -1    x01 x02 x03 x04

I am a little late but for Python 3 9 1 this worked for me and removed the -b prefix  print outputCode decode

you can use this code for showing or print    lt byte object gt  decode  quot utf-8 quot    and you can use this for encode or saving    lt str object gt  encode  utf-8

If the bytes use an appropriate character encoding already  you could print them directly   sys stdout buffer write data    or  nwritten   os write sys stdout fileno    data     NOTE  it may write less than len data  bytes
