Hi !!

first of all, thank you...
Some time ago I saw a code in gist of a Des3
I have basic level knowledge in python but I encounter the following problem in this line :

Code: Select all

                if _pythonMajorVersion < 3:
			return ''.join(result)
		else:
			return bytes.fromhex('').join(result)

bytes.fromhex('')

MicroPython doesn't support bytes.fromhex

I think it should be added -- see the PR I raised here: https://github.com/micropython/micropython/pull/7539

What is the code actually trying to do though? MicroPython is also only Python 3, so you don't need the if statement. I feel like the whole thing should just be

Code: Select all

return b''.join(result)
