Python3中基于文本的冒险

Question

我正在研究一个基于文本的RPG，但是我发现了很多问题，比如：

• 进店后不能去任何地方
• 由于某种原因，我无法进入“酒馆”；以及
• 计算机只显示"buy is not defined in crossbow"。在

代码：

gold = int(100)
inventory = ["sword", "armor", "potion"]

print("Welcome hero")
name = input("What is your name: ")
print("Hello", name,)
# role playing program
#
# spend 30 points on strenght, health, wisdom, dexterity 
# player can spend and take points from any attribute

classic = {"Warrior",
         "Archer",
         "Mage",
         "Healer"}
print("Choose your race from", classic,)
classicChoice = input("What class do you choose: ")
print("You are now a", classicChoice,)

基于Kevin的回答，这里有一个压缩了冗余的版本，因此您可以通过在顶部附近添加一个新的def go_xyz(): ...来添加一个新的位置。在

def go_shop():
    print("Welcome to the shop!")
    #...etc

def go_tavern():
    print("You enter the tavern...")
    #...etc

def go_forest():
    print("You enter the forest...")
    #etc

places = {name[3:]:globals()[name] for name in globals() if name.startswith('go_')}
placenames = ', '.join(places)

inventory = ['book']
retry = False

while True:
    if not retry:
        print("Here is your inventory: ", inventory)
    else:
        print("I do not know that place")
    print("Where do you wish to go?")
    print("Possible places: ", placenames, '.')
    choice = input("? ")
    try:
        places[choice]()
        retry = False
    except KeyError:
        retry = True
