Eingabe vom Benutzer wird immer als ungültig in Python

Question

Ich bin ein Turn-basierten Simulator von Pokemon bauen. Genauer gesagt, der Kampf zwischen Pikachu und Spearow (mit einigen kreativen Freiheiten). Das Problem ist, dass, wenn ich den Benutzer frage, welche Bewegung er verwenden möchte, gibt es immer die Antwort zurück, dass die Bewegung ungültig ist.

Answer 1

• Es gibt einfache Anführungszeichen um user_choice ('user_choice'). Entferne sie.
• Sie geben keinen Wert von standby_battle_text() Funktion zurück. Daher wird user_choice innerhalb attack() Methode von monster1 nicht erkannt. Also, Sie sollten return user_choice von standby_battle_text()
