Convert Hex String to ASCII String in Python

The bytearray.decode(encoding, error) function in Python3 accepts a byte array as input and decodes it according to the encoding scheme given in the encoding parameter.

To decode a string in Python 3, we must first convert it to a byte array and then use the bytearray.decode() method. To begin, use the bytearray.fromhex(string) method to convert the string to a byte array.

hex_str = "0x865a6c"[2:]

# convert hex string to ASCII string
bytes_array = bytes.fromhex(hex_str)

The example code below shows how to use Python’s bytearray.decode() and bytearray.fromhex(string) methods to convert a hex string to an ASCII string.

Program :

# Python program to convert hex string to ASCII string

# hexadecimal string
hex_str = "0x68656c6c6f"[2:]

# convert hex string to ASCII string
bytes_array = bytes.fromhex(hex_str)
ascii_str = bytes_array.decode()

# printing ASCII string
print('ASCII String:', ascii_str)

Output:

ASCII String: hello
