如何進(jìn)行連續(xù)輸入？我希望玩家能夠在他想要的任何時(shí)候編寫菜單，而不僅僅是在程序開始時(shí)？print("\nWelcome to the nature center. What would you like to do?")choice = ''while choice != 'q': print("\n[1] Enter 1 to take a bicycle ride.") print("[2] Enter 2 to go for a run.") print("[3] Enter 3 to climb a mountain.") print("[q] Enter q to quit.")choice = input("\nWhat would you like to do? ")if choice == '1': print("\nHere's a bicycle. Have fun!\n")elif choice == '2': print("\nHere are some running shoes. Run fast!\n")elif choice == '3': print("\nHere's a map. Can you leave a trip plan for us?\n")elif choice == 'q': print("\nThanks for playing. See you later.\n")else: print("\nI don't understand that choice, please try again.\n")

不確定您的縮進(jìn)是否不正確，但您可以永遠(yuǎn)循環(huán)（while True），然后break在您需要時(shí)：
print("\nWelcome to the nature center. What would you like to do?")
while True: # Loop through indefinitely
print("\n[1] Enter 1 to take a bicycle ride.")
print("[2] Enter 2 to go for a run.")
print("[3] Enter 3 to climb a mountain.")
print("[q] Enter q to quit.")
choice = input("\nWhat would you like to do? ")
if choice == '1':
print("\nHere's a bicycle. Have fun!\n")
elif choice == '2':
print("\nHere are some running shoes. Run fast!\n")
elif choice == '3':
print("\nHere's a map. Can you leave a trip plan for us?\n")
elif choice == 'q':
print("\nThanks for playing. See you later.\n")
break # Exit the loop here
else:
print("\nI don't understand that choice, please try again.\n")

我認(rèn)為您還需要在您的while：
print("\nWelcome to the nature center. What would you like to do?")
choice = ''
while choice != 'q':
print("\n[1] Enter 1 to take a bicycle ride.")
print("[2] Enter 2 to go for a run.")
print("[3] Enter 3 to climb a mountain.")1
print("[q] Enter q to quit.")
choice = input("\nWhat would you like to do? ")
if choice == '1':
print("\nHere's a bicycle. Have fun!\n")
elif choice == '2':
print("\nHere are some running shoes. Run fast!\n")
elif choice == '3':
print("\nHere's a map. Can you leave a trip plan for us?\n")
elif choice == 'q':
print("\nThanks for playing. See you later.\n")
else:
print("\nI don't understand that choice, please try again.\n")
