【问题描述】:
大家好,我是 python 的初学者,我正在尝试制作自己的文本 rpg 游戏。我已经为英雄在商店中购物做了一个方法,但由于某种原因,我每次到达商店时都会收到此错误:
nboundLocalError: 赋值前引用了局部变量“arm”
有人可以向我解释这意味着什么以及如何解决它吗?谢谢

dagger = ('Dagger', 0, 5)
sword = ('Sword', 0, 10)

else:
print()
print("Welcome to the Larkville shop! What would you like to buy?\n1. Weapons\n2. armor\n3. Go back")
selection = int(input("Enter a value: "))
if selection == 1:
print("Weapons shop")
print("1. Bronze Dagger: $7\n2. Bronze Sword: $50 3.Rusty Sword $60")

elif wpnselection == 1:
if hero.ac<20:
print("You donthave enough gold to buy this yet ")
