binascii is a widely used Python library for ASCII-encoded binary representations. It contains several methods for converting to binary from ASCII or hex, and vice versa.
binascii.unhexlify is a method in the
binascii library. It returns the binary string that is represented by any hexadecimal string.
unhexlify works opposite of the method b2a_hex(), or
The data being converted must contain an even number of hex digits; otherwise it raises
import binascii # simple command to see how unhexlify works # hex value of A is 41 print(binascii.unhexlify('41')) # data x = "Hello" # first convert string to bytes res = bytes(x, 'utf-8') # convert to hex w = binascii.hexlify(res) # unhexlify the hex print(binascii.unhexlify(w))
