Przyporządkowywanie zmiennej nadrzędnej do zmiennej podrzędnej

Nie wiem do końca jak temat nazwać. Generalnie mój problem jest taki. Piszę gierkę tekstową dla zabawy:
W skrócie wygląda to tak.
Na początku mamy input powitalny z 3 możliwymi opcjami:
a, b, c.
Po wybraniu b pokazuje się 5 opcji
po wybraniu dowolnej liczba opcji się zmniejsza. Nie mniej finalną opcja jest opcja wyjściowa.
Czyli w pierwszym kroku wybieramy b, potem a, znowu a aż w końcu wybranie a automatycznie jest równe opcji c z pierwszego wyboru.

if beginning == "a":
    marketX = input("Welcome on the market of Xarthas, what you plan to do? \n [a] Go to horse merchant,\n "
                    "[b] Go to armor merchant,\n[c]Go to wine merchant,\n [d]Go to weapon merchant "
                    "\n[e] Go to wheat merchant \n[f] Try to sell your goods")
    if marketX == "a":
        print("Greetings, are you looking for new steed?")
    elif marketX == "b":
        print("Greetings, I see that you are not warrior, please let me show you my best crafts")
    elif marketX == "c":
        print("Here, take a look at the finest wines in Xarthas")
    elif marketX == "d":
        print("Welcome in the finest armory of this city")
    elif marketX == "e":
        print("Welcome in Jacobsen & Sons")
    elif marketX == "f":
        print("You set up your stool and wait for buyer of your stuff")
elif beginning == "b":
    tavernX = input("Welcome in Hanging Bear. You can: \n [a] buy a beer for 5 talars. \n "
                    "[b] buy food for you for 15 talars .\n "
                    "[c] rent a room for 1 gulden. \n [d] buy food for your horses for 2 guldens. \n [e] leave tavern.")

    if tavernX == "a":
        totalMoney = totalMoney - beerPriceX
        tavernXa = input("You feel happier, yet your pocket is lighter. You have " + str(totalMoney) + " total"
                         " Do you wish to do anything else? You can:\n [a] buy food for you for 15 talars. \n "
                         "[b] rent a room for 1 gulden. \n [c] buy food for your horses for 2 guldens. \n "
                         "[d] leave tavern.")
        if tavernXa == "a":
            totalMoney = totalMoney - foodPriceX
            tavernXaA = input(" You feel healthier, but your money bag contains only " + str(totalMoney) + " now. "
                              "You can either:\n [a]rent a room for 1 gulden. \n "
                              "[b] buy food for your horses for 2 guldens."
                              "\n [c] leave tavern. ")
            if tavernXaA == "a":
                totalMoney = totalMoney - rentPriceX
                tavernXaAa = input("Yaawn, that was good night Now you posses only a mere " + str(totalMoney) + ""
                                   " guldens. You can: \n [a] feed your horses for 2 guldens.\n [b] leave the tavern.")
                if tavernXaAa == "a":
                    totalMoney = totalMoney - horseFoodX
                    tavernXaAaA = input("Now you have " + str(totalMoney) + " guldens and your horses are well feed. "
                                        "Having none activities here, you decided to leave tavern. Now you can :\n"
                                        "[a] go to market \n[b] leave the city")
                    if tavernXaAaA == "a":
                        tavernXaAaA = marketX
                    else:
                        tavernXaAaA = outskirtsX

           elif beginning == "c":
    outskirtsX = input("You are at outskirts of the city")
       

Jak najszybciej/najprościej zrobić by zmienna lokalna tavernXaAaA zwracała input ze zmiennej outskirtsX? Co robię źle?

Najpierw robisz override zmiennej tavernXaAaA przypisując do niej to, co siedzi w outskirtsX, a potem do outskirtsX wrzucasz coś nowego - czyli input użytkownika. Trochę tak, jakbyś w C napisał:

int a = 10;
int b = 20;
b = a;
a = 30;
printf("%d", b);

I oczekiwał, że zobaczysz 30 :)

Musisz mieć jakiś ogólny handler, który 'skanuje' obecny status i wykonuje przypisane akcje. Mozesz zaimplementować to za pomocą pętli while. Jest to nie jako state machine (wygooglaj koncepcję). Np.:

Niby wraca mi na początek ale jedynie na początek "tavernX"
Chciałbym by wracało do wyboru nadrzędnego

Możesz zacząć refaktoring od drobnych zmian. Np. przenieść tfragmenty kodu do funkcji. Stworzę też bardzo prostą klasę State która będzie przechowywać obecne miejsce i stan $:

Przykład:

class State:
    def __init__(self):
        # look into decimal class for better money related numbers calcs
        self.money = float(40.30)
        self.place = None

Nie testowałem tego kodu po prostu napisałem w poście więc mogą być literówki lub drobne błędy.

W sumie to w ogóle jeśli fabuła tej gry jest taka "drzewiasta", to może logicznie byłoby machnąć sobie w kodzie jakieś drzewo/graf lokacji / zdarzeń powiązanych na zasadzie przyczyna (akcja) -> skutek (nowy stan/lokacja/konwersacja/whatever) z nowymi opcjami czy coś zamiast jakichś turbo-ifo-pętli :P Może łatwiej byłoby Ci żonglować stanami w czymś takim :)

Powiedzmy że machniesz sobie taki building block - w dużym uproszczeniu:

class Node:
  def __init__(self, description=None):
    self.description = description or 'Unknown location'
    self._visited = False
    self._children = {}
  
  def add_child(self, child, key):
    if key in self._children .keys():
      raise KeyError('Key "{}" is already taken'.format(key))
    self._children [key] = child
  
  def get_child(self, key):
    return self._children.get(str)
  
  @property
  def options(self):
    return list(self._children.keys())
  
  def visit(self):
    self._visited = True

No i cyk, masz coś w stylu drzewka które możesz poskładać do kupy. Od biedy dałbyś radę chodzić po tym i/lub poskładać to w jakiś graf:

>>> question = Node('The Drunken Merchant tells you a really bad joke. How do you respond?')
>>> a = Node('"Hahaha" - you try to sound as believably as possible. The Drunken Merchant is so drunk he wouldn\'t notice, but better safe than sorry. You get your bargain.')
>>> b = Node('"He.. he..." - you force yourself to laugh. The Drunken Merchant is too drunk to notice and gives you a bargain.')
>>> c = Node('"That wasn\'t funny at all!" - you fuss at the merchant. "Get lost, loser!" - the Drunken Merchant responded and stumbled away.')
>>> question.add_child(a, 'A) Laugh')
>>> question.add_child(b, 'B) Laugh half-heartedly')
>>> question.add_child(c, 'C) Tell the merchant his joke was bad')
>>> question.options
['A) Laugh', 'B) Laugh half-heartedly', 'C) Tell the merchant his joke was bad']
>>>

Choć być może lepiej byłoby ich nie składać do kupy w jedną wielką strukturę, tylko trzymać te węzły osobno i w każdym tylko np. identyfikatory dzieci, albo w ogóle zrobić osobną macierz połączeń między takimi elementami fabuły, a stan gry trzymać obok, albo dorzucić do węzła info kto jest rodzicem... no możliwości masz od kopa.
