Back in the day, I wrote this x86 emulator just for fun: https://github.com/ForceBru/PyVM, and to this day, my implementation of instruction parsing (disassembly) is bugging me because it's a mess and doesn't seem correct at all, even though it kind of works. However, after a couple of years of occasionally trying to find some kind of "proper" algorithm for machine code disassembly, I couldn't find anything... noteworthy, or well-known, or widely used.
BAP (https://github.com/binaryanalysisplatform/bap), angr (https://angr.io/) and others already do what you're asking for as more purpose-built solutions for dynamic analysis. Angr specifically in python.
