将用户输入从函数存储到变量

Question

我试图捕获函数中用户的输入并分配给函数之外的变量，该变量稍后可以在代码中引用：

  def WepSelection():
    weapon_options = ["1", "2", "3"]
    y = ""
    while y not in weapon_options:
        print("""Welcome, traveler. Before you begin your journey, please choose 
from one of the following three weapons:

            1) Sword
            2) Spear
            3) Bow and Arrow
            """.format(name))
           y = input("Please pick a weapon by entering the corresponding number (1, 2 or 3): ")

    if y == weapon_options[0]:
        y = "sword"
        print("You have select the", y.name)
        return y

    elif y == weapon_options[1]:
        y = "spear"
        print("You have select the", y.name)
        return y

    elif y == weapon_options[2]:
        y = "bow_arrow"
        print("You have select the", y.name)
        return y

最终，我希望发生的是，用户选择中的“y”变量（“sword”，“spear”或“bow_arrow”字符串）可以分配给变量，例如“selected_weapon” “这可能在功能之外。

例如，如果用户在函数中选择1，则外部变量selected_weapon =“sword”。

非常感谢。
