You can replace the string variable s with your hex string you want decoded. Codecs PackageĪn alternative way to decode a hex string that is universal and works for both Python 2 and Python 3 on various programming environments is using the codecs.getdecoder() function. Otherwise, Python will raise an error if your hex string cannot be decoded because it doesn’t decode anything in the code you chose (ASCII or Unicode etc.). For instance, ‘68656c6c6f’ will actually decode like so: You could then verify that it is a hexadecimal number by trying to convert it to a decimal with int () : try: decimal int (num, 16) interpret the input as a base-16 number, a hexadecimal. Of course, you need to make sure that the hex string actually can be decoded, i.e., two digits together represent one Unicode or ASCII symbol. hex () converts an integer number to a hex representation, a string. ⭐ Recommended Tutorial: 4 Pythonic Ways to Convert Hex to ASCII in Python If you want to decode to ASCII, simply pass ‘it 'ascii' into the code() method like so: > omhex('68656c6c6f').decode('ascii') The most modern would be using subprocess.checkoutput and passing textTrue (Python 3.7+) to automatically decode stdout using the system default coding: text subprocess.checkoutput('ls', '-l', textTrue) For Python 3. Share Follow answered at 18:54 unbeli 29.4k 5 55 56 9 Unless the decoded string is actually utf-8, I would recommend using decode ('ascii') instead. Unicode ( is a specification that aims to list every character used by human languages and give each character its own unique code. The previous example uses the Unicode 'utf-8' encoding scheme. 3 Answers Sorted by: 138 Something like: > omhex ('4a4b4c').decode ('utf-8') 'JKL' Just put the actual encoding you are using. Python’s string type uses the Unicode Standard for representing characters, which lets Python programs work with all these different possible characters. ⭐ Recommended Tutorial: How to Convert a Hex String to a Bytes Object in Python? Here’s why you use the first part of the expression-to obtain a bytes object first: > omhex('68656c6c6f') ![]() Here’s how you can chain the two methods in a single line of Python code: > omhex('68656c6c6f').decode('utf-8') This work implements an intelhex Python library to read, write, create from scratch and manipulate data from Intel HEX file format. For example, b'hello'.decode('utf-8') yields 'hello'. The Intel HEX file format is widely used in microprocessors and microcontrollers area (embedded systems etc) as the de facto standard for representation of code to be programmed into microelectronic devices.
