import time

difficulty = input("Enter difficulty (easy, medium, hard): ").lower().strip()

while difficulty not in ["easy", "medium", "hard"]:
    print("Please enter a valid difficulty level.")
    difficulty = input("Enter difficulty (easy, medium, hard): ").lower().strip()
    time.sleep(0.5)

print("Difficulty set to:", difficulty)

Difficulty set to: easy
