Beispiel für ein Snake-Spiel, geschrieben in Python_python

In diesem Artikel werden hauptsächlich Beispiele für das in Python geschriebene Snake-Spiel vorgestellt. Es ist ein praktisches Werk, das Spaß macht und Freunde, die es brauchen, darauf verweisen kann.

Dies ist das erste Mal Um diese Art von Vergleich in Python zu schreiben, ist es praktisch und macht Spaß, es einfach zu üben

Spielbeschreibung:

* P-Taste steuert „Pause/Start“
* Pfeiltasten steuern die Richtung der Schlange

Der Quellcode lautet wie folgt:
