[Python] Binary-Hex a NoneType Object ? [SOLVED]

Question

I want to binary-hexlify the s value using the 'b' tag in the ( )
print(binascii.hexlify(b(s))
or what ?
for more knowledge what I'! trying to do is doing it like this code :
print(binascii.hexlify(b'hello worl'))

Answer 1

SOLVED
s = "hello"
print(binascii.hexlify(bytes(s.encode('ascii'))))

Answer 2

@Krik Schafer I think your getting closer to the answer what I'm trying to do is is printing the NoneType with the 'b' tag now you're wondering which 'b' tag I With this one

print(binascii.hexlify(b'hello')
^
did you get it I'm trying to use that tag with a NoneType

Answer 3

@Krik Schafer I know how to convert but I don't know how to do that with NoneType like should I use [] or {} to remind about the NoneType in the hexlify function attribute like in Ruby "#{reminding or some value}" can I do that ?

Answer 4

By chance do you mean ASCII null?

c=chr(0)
print(c.encode())

Output:
b'\x00'

(Otherwise I'm trying to figure out what about the None value could help, e.g. from print(dir(None)) -- I don't see bytes conversion there and I'm not familiar with binascii(); I'll look though)

Answer 5

# Not sure on this, especially NoneType... but here are some things in the area I think you're asking.

# This outputs a compatible type as binary 1/0's
print("{:b}".format(97))

# b'...' is a bytes object and acts like a list (array)
# Prints byte 0 (read the docs, below)
print("{:b}".format(b'a'[0]))

# ord() = ordinal character value (ASCII)
print("{:b}".format(ord('a'))) # a = ASCII 97

# Hex
print("{:#x}".format(97))
# strip 0x
print("{:x}".format(97))

# Help for bytes objects.
print(b''.__doc__)

# Run this alone, it sometimes triggers timeout
#print(help(b''))

Answer 6

Well, I wandered around some ideas but I'm not seeing anything direct, which means hackish solutions.

None is a singleton constant representing the absence of value and special behavior:
https://docs.python.org/3/library/constants.html#None

These unsurprisingly return the same output:
print(...hexlify(None.__repr__().encode()))
print(...hexlify(b"None"))

...which leaves in my mind extending the NoneType class (or binascii's behavior) to return a None-position lookup table that's somehow added to encoded text, using a custom alphabet, or setting aside a hex value not already used within the current alphabet as a None placeholder.
