I've got two bytes-type variable that I've concatenated (separated by a space) so I can send it as one variable to a server (socket programming). What I'm trying to figure out is how to then separate them and assign them to their original variables using regular expressions. I've consulted [regular expressions parsing a binary file](https://stackoverflow.com/questions/5618988/regular-expression-parsing-a-binary-file) but it wouldn't work for me. [Here](https://prnt.sc/hjjn54) is my output after trying the expression as so just to get the cipher variable

```
ciphertext = re.match(b'\S', ciphertext)

```

It generally only matches the first couple characters and returns an object, which isn't what I'm wanting. What am I doing wrong? 

edit: I'm probably doing it the hard way. Honestly, any recommendation on how to send 2 bytes objects over a socket using UDP. Its proving really difficult
