如何正确声明函数之外的变量，以便在微型文本冒险中运行test()

Question

我正在做一个迷你文字角色扮演游戏，你必须与国王共进晚餐。我基本上是在声明if语句中的变量，根据用户输入的内容，使变量成为一个特定的值。我想我需要在函数之外声明它们，但我不确定我对python相当陌生。

def creation_role():
    print("""What is your character's role?\n
A: Lord (Base stats: Charisma  7, Wit 3, Valor 5)
B: Peaseant (Base stats: Charisma  5, Wit 7, Valor 3)
C: Knight (Base stats: Charisma  3, Wit 5, Valor 7)""")
    role = input("> ")
    role = role.lower()

    if "a" in role:
        role = "lord"
        charisma = 7
        wit = 3
        valor = 5
    elif "b" in role:
        role = "peaseant"
        charisma = 5
        wit = 7
        valor = 3
    elif "c" in role:
        role = "knight"
        charisma = 3
        wit = 5
        valor = 3
    else:
        error()
        creation_role()



def creation_home():
    print("""Choose where you hail from:\n
A. Hillford: Lush foliage as far as the eyes can see, the enchanted trees
bear the fruit of wisdom.\n
B. Aermagh: A land as beautiful as it is cold, it's people learn strength
from the first day of life fighting frostbite as a babe.\n
C. Venzor: The rich island nation some call it the pearl of Skystead,
In recent decades it's seen outsiders giddy to make quick riches.""")
    home = input("> ")
    home = home.lower()

    if "a" in home:
        home = "Hillford"
        wit + 2
    elif "b" in home:
        home = "Aermagh"
        valor + 2
    elif "c" in home:
        home = "Venzor"
        charisma + 2
    else:
        error()
        creation_home()

def test():
    creation_role()
    creation_home()
    print(home, "\n", charisma, "\n", wit, "\n", valor)

test()

Answer 1

测试函数不知道主变量、魅力变量、智慧变量和勇敢变量。

为了让它了解它们，您需要从其他函数中返回这些值。例如：

def creation_role():
  ...logic
  return role, charisma, wit, valor

然后，您可以在测试中使用这些变量。

def test():
    role, charisma, wit, valor = creation_role()
    home, charisma, wit, valor = creation_home(charisma, wit, valor)
    print(home, "\n", charisma, "\n", wit, "\n", valor)

注意，还需要修改creation_home函数以接受这些变量，并返回新值。

def creation_home(charisma, wit, valor):
    ....
    return home, charisma, wit, valor

编辑:在修改统计数据时还会出现一些语法错误。它应该是

wit += 2

而不是

wit + 2

Answer 2

您应该创建类MiniText或其他什么，然后将这些变量初始化为init的一部分。我看到的另一个问题是

charisma + 2

您没有存储结果值。
