在while循环中，除elif user_choice.upper() == "C"
外，所有if和elif语句都有效。我试着输入选项C，希望程序打印"行驶里程";但是程序再次要求输入
# Game info
print("Welcome to camel")
print("You have stolen a camel too make your way across the great Mobi desert")
print("The natives are chasing you and want their camel back. Survive and run out the natives")
# Storing values in variables
miles_travelled = 0
drinks_canteen = 3
natives_travelled = -20
camel_tiredness = 0
players_thirst = 0
done = False
# Making the loop
while not done:
print("A. Drink from your canteen")
print("B. Ahead moderate speed")
print("C. Ahead full speed")
print("D. Stop for the night")
print("E. Status check")
print("F. Quit")
user_choice = input("Your choice? ")
if user_choice.upper() == "A":
if drinks_canteen == 0:
print("No drinks in your canteen")
user_choice = input("Your choice? ")
elif drinks_canteen != 0:
drinks_canteen -= 1

您缺少一对括号。将elif user_choice.upper == "C":替换为elif user_choice.upper() == "C":。完整代码如下:
# Game info

print("You have stolen a camel too make your way across the great Mobi desert")
print("The natives are chasing you and want their camel back. Survive and run out the natives")

在user_choice处缺少一对括号。upper = "此外，您需要将if语句分成两个部分:一部分用于获取输入，另一部分用于计算效果。最后，您需要删除打印后的用户输入("No drinks in your canteen")。下面是更新后的代码:
