Python 2.7 vs Python 3.8 (Socket Module)

[MattB]

Hello. I have developed a program in Python 3.8 that uses socket to communicate. It works great with 3.8. It will return data back in hex like it should. See below.

I have found python 3.8 socket module returns in bytes where python 2.7 return a string.

I am stuck using python 2.7 because the software I am using on the project requires it. I have tried to convert it many ways and I have had no luck. Any help will be appreciated.
