设计一个RPG类，坚持我的循环

Question

所以首先为糟糕的代码风格道歉，这是我的第一个大项目（我的python类的最后一个项目）。我卡在循环设置我需要从“主菜单”显示菜单功能移动到移动菜单功能，因为它现在运行时，选择A从显示菜单什么都没有发生，选择b和c工作得很好。我想这是我如何设计循环的问题，以及从一个循环到另一个循环的中断/移动。你知道吗

就实际的运动而言，我做了一个很好的尝试，但是让菜单工作对于测试运动是至关重要的，所以这就是我在这方面的工作。你知道吗

如有任何意见或建设性的批评，我们将不胜感激。谢谢

    if x == 0:

            print("Sh*ts Sandy broski")
        elif y == 2:

如果我理解你的问题，我会这样做的。。。然后你只需要为每个菜单设置一个菜单列表的格式，它就可以处理几乎所有的事情

def get_player_choice(choices):
    labels,actions = zip(*choices)
    choice_actions = dict(enumerate(actions,1))
    for choice_id,label in enumerate(labels,1):
        print "%d. %s"%(choice_id,label)
    while True:
        result = raw_input("Select Option:")
        try:
            return choice_actions[int(result)]
        except TypeError:
            print "ERROR: Please enter a number choice!"
        except KeyError:
            print "ERROR: Unknown Choice!"

def LookAround():
     print "You See Something!"
def Quit():
     print sys.exit       

menu_a = [
("Look Around",LookAround),
("Quit!",Quit)
       ]
fn = get_player_choice(menu_a)
fn()
