Just posting this so I can search for it later, as it always seems to stump me:

As question: how to print a binary (bytes
) string in Python 3, without the b'
prefix?
This question is related to

string
python-3.x
Use decode
:
print(curses.version.decode())
# 2.2
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
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 :
<byte_object>.decode("utf-8")
and you can use this for encode or saving :
<str_object>.encode('utf-8')
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()
:
>>> x = b'\x01\x02\x03\x04'
>>> print(repr(x))
b'\x01\x02\x03\x04'
>>> print(repr(x)[2:-1])
\x01\x02\x03\x04
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
