Body: <p>I have developed a chess engine in Python with negamax, alpha beta and piece square table. I want to &quot;compile&quot; my code into a UCI compatible one so I can load it to Arena GUI, but I have no idea at all how to do that and every time I search for information I found it very confusing and counterintuitive. Could someone give me a light, a direction please, cause I don't know how to even begin ...</p>
  <p>Note: I use Python chess module in my code and the moves are returned in UCI format since I use the <code>return move.uci()</code> method, but I don't understand if this is enough or how to load my code to Arena GUI, I have just few experience developing.</p>

Comments.Text: Put simply, your engine needs to write certain information to standard output, which the GUI will read, and you need to read certain information the GUI will send via standard input. What this "certain information" is is specified in the UCI protocol Ferdy linked.
