I need to convert user input to Hex, but with NULL characters between each character.
Eg:
User input = 111
Output = b'3100310031
My best attempt looks like this, but it's nowhere near...
import binascii
content5 = rb"111"
print(content5)
joiner = "00"
content4 = binascii.hexlify(content5)
print(content4)
content3 = joiner.join(str(content4))
print(content3)
content2 = bytes(content3, 'utf-8')
print(content2)
content = binascii.hexlify(content2)
print(content)
But this returns:
b'111'
b'313131'
b00'00300100300100300100'
b"b00'00300100300100300100'"
b'62303027303033303031303033303031303033303031303027'
b'3632333033303237333033303333333033303331333033303333333033303331333033303333333033303331333033303237'
Any help would be greatly appreciated! 😁
Hexlify change every byte if the input byte string to its (2 bytes) hexa representation. Just process one byte at a time and join the result:
import binascii
content5 = rb"111"
print(content5)
joiner = "00"
content4 = joiner.encode().join(binascii.hexlify(bytes((i,))) for i in content5)
print(content4)
It gives as expected:
b'111'
b'3100310031'

I did some search for this question, but I can not find relevant answer. I am trying to convert some string form input() function to Base64 and from Base64 to raw string of 1s and 0s. My converter is working, but its output are not the raw bits, but something like this: b'YWhvag=='.
Unfortunately, I need string of 1s and 0s, because I want to send this data via "flickering" of LED.
Can you help me figure it out please? Thank you for any kind of help!
import base64
some_text = input()
base64_string = (base64.b64encode(some_text.encode("ascii")))
print(base64_string)
If I have understood it corretly you want binary equivalent of string like 'hello' to ['1101000', '1100101', '1101100', '1101100', '1101111'] each for h e l l o
import base64
some_text = input('enter a string to be encoded(8 bit encoding): ')
def encode(text):
base64_string = (base64.b64encode(text.encode("ascii")))
return ''.join([bin(i)[2:].zfill(8) for i in base64_string])
def decode(binary_digit):
b = str(binary_digit)
c = ['0b'+b[i:i+8] for i in range(0,len(b), 8)]
c = ''.join([chr(eval(i)) for i in c])
return base64.b64decode(c).decode('ascii')
encoded_value = encode(some_text)
decoded_value = decode(encoded_value)
print(f'encoded value of {some_text} in 8 bit encoding is: {encoded_value}')
print(f'decoded value of {encoded_value} is: {decoded_value}')
I have a table in a database which stores image files in varbinary(max) type. I would like to extract, convert and save the image file. Then, I used the cast as varcharmax to extract:
cast([IMG_FILE] as varchar(max))
The result of this cast looks like a hex string (I've removed part of string to protect the privacy of the person):

I tried to used this hex string in a online tool (https://codepen.io/abdhass/full/jdRNdj), and the image is corrected displayed (remembering that I've cutted part of string to preserve the persons privacy):
Then, I've tried to take this hex string and tried to convert to a image file using python3. I've been trying a lot of things (the majority found here), but until now, I coudn't save the correct file.
Saving directly doesn't generate the image.
with open(photo_path + 'file.jpg', 'wb') as new_jpg:
new_jpg.write(hexString)
Using binascii.unhexlify returns "Non-hexadecimal digit found"
binascii.unhexlify(hexString)
Converting to int/bin returns invalid literal for int() with base 16:
bin(int(hexString, 16))[2:]
I would like to know how to solve this problem? That is, I would like to take this hex string and save a image file in my computer.
If I have string without \x then I can convert every two chars to integer value, create bytearray and save it

Because string in your question is incomplete so it creates incomplete image.
But with data from link it create correct JPG file.
EDIT:
It seems you have raw string and \x is treated as normal string, not part of byte \xff - and you have to remove \x at start using using text = text[2:]
text = r'\xffd8ff...'
integers = []
text = text[2:]

value = int(text[:2], 16)

EDIT:
Simpler version with standard module codecs. It still need to remove \x from string.
If you have bytes:
text = b'\\xffd8ff...' # bytes
import codecs
text = text[2:] # remove `\x`
data = codecs.decode(text, 'hex_codec')
with open('output.jpg', 'wb') as fh:
fh.write(data)
If you have string - then you have to first encode() to bytes:
text = '\\xffd8ff...' # string
import codecs
text = text.encode() # bytes
text = text[2:] # remove `\x`
data = codecs.decode(text, 'hex_codec')
with open('output-1.jpg', 'wb') as fh:
fh.write(data)
I want to convert the string 400AM49L01 to a hexadecimal form (and then into bytes) b'x\34\x30\x30\x41\x4d\x34\x39\x4c\x30', so I can write it with pySerial.
I already tried to convert the elements of a list, which contains the single hexadecimals like 0x31 (equals 4), into bytes, but this will result in b'400AM49L01'.
device = '400AM49L01'
device = device.encode()
device = bytes(device)
device = str(binascii.hexlify(device), 'ascii')
code = '0x'
text = []
count = 0
for i in device:
if count % 2 == 0 and count != 0:
text.append(code)
code = '0x'
count = 0
code += i
count += 1
text.append((code))
result = bytes([int(x, 0) for x in text])
Really looking forward for your help!
The following code will give the result you expecting.
my_str = '400AM49L01'
"".join(hex(ord(c)) for c in my_str).encode()
# Output
# '0x340x300x300x410x4d0x340x390x4c0x300x31'
What is it doing ?
In order to convert a string to hex, you need to convert each character to the integer value from the ascii table using ord().
Convert each int value to hex using the function hex().
Concatenate all hex value generated using join().
Encode the str to bytes using .encode().
Regards!
This question is similar to this one here but if I put this into this code like so:
import base64
theone = input('Enter your plaintext: ')
encoded = str(base64.b64encode(theone))
encoded = base64.b64encode(encoded.encode('ascii'))
encoded = encoded[2:]
o = len(encoded)
o = o-1
encoded = encoded[:o]
print(encoded)
it raises this problem:
line 58, in b64encode
encoded = binascii.b2a_base64(s, newline=False)
TypeError: a bytes-like object is required, not 'str'
And then if I remove this line of code:
encoded = base64.b64encode(encoded.encode('ascii'))
then it raises the same error. I'm not sure what to do from here and I would be grateful for any help.
You seem to be having problems with bytes and strings. The value returned by input is a string (str), but base64.b64encode expects bytes (bytes).
If you print a bytes instance you see something like
b'spam'
To remove the leading 'b' you need to decode back to a str.
To make your code work, pass bytes to base64.b64encode, and decode the result to print it.
>>> theone = input('Enter your plaintext: ')
Enter your plaintext: Hello World!
>>> encoded = base64.b64encode(theone.encode())
>>> encoded
b'SGVsbG8gV29ybGQh'
>>> print(encoded.decode())
SGVsbG8gV29ybGQh
At the moment I have a byte stream of a string that is received by my Python code and must be converted into a string. For now I managed to extract each character, convert them and append them to a string individually. The code looks something like this:
import struct
# The byte stream is received and stored in byte_stream
text = ''
i = 0
while i < len(byte_stream):
text = text + struct.unpack('c', byte_stream[i])[0]
i += 1
print(text)
But that surely cannot be the most efficient way... Is there a more elegant way to do achieve the same result?
From Convert bytes to a Python string:
byte_stream = [112, 52, 52]
''.join(map(chr, bytes))
