How to cast bytes to an int and back to the same bytes?

I have an arbitrary byte in Python that I want to cast into a 64 bit integer and back into the same byte.

I am currently, using this to turn the bytes into an int, where x is a byte I am given:

int.from_bytes(x, "little")  

But I'm struggling on how to use int.to_byte() to convert it back to the same bytes because I'm unsure what to put for length, nothing seems to create the equivalent byte?
