How do I convert a list of ASCII "Bytes" in Python into Hex Bytes

Question

I have a list of ASCII "bytes", that I need to convert to hex, and then send over a serial port.

For example, take the following list:

list_to_send=['FE','FE','98','E0''07', 'D2', '00','FD"]

I'd like to convert each byte to hex so that for example the first byte would look like this:

b'\xfe'

I've tried using binascii, but I think my usage is incorrect.

Thanks!

if you are using Python 3.5 and above,then use this

b'\xFE'.hex()

And if you wanna use binascii ,then :

import binascii
binascii.hexlify('FE'.encode('utf8'))

I'm a bit confused. {b'\xFE'} would be my desired output, not the input. – Marty Sullaway Apr 25 '20 at 19:27

using join()

str="b'"
for x in list_to_send:
    str=str+"\x"+x
str=str+"'"
