[PYTHON] Ich bin ein Anfänger, kann ich mir Weisheit ausleihen?

Ich bin neu in der Programmierung. Es ist eine sehr persönliche Angelegenheit, aber ich kann es nicht tun. Könnten Sie mir also etwas Weisheit verleihen? Nachdem Sie das folgende Programm ausgeführt und das Spiel gespielt haben, wird der unten gezeigte Bildschirm angezeigt. Es heißt, WPM war 0.0, was für mich 30,40 sein sollte. Könnten Sie mir bitte sagen, was falsch ist und wo es behoben werden kann?
