Python（RenPy）：执行函数的文本按钮，它们不会在每次按下时显式调用该函数

Question

在我正在进行的游戏中，我使用一个数组来跟踪玩家所在公司的当前统计数据，并使用以下函数来编辑数组

init python:

#The following store item objects, which include an array of their own stats
#Stores currently owned equipment
   Equipment = []
#Stores items available to buy
   Items = []
#Stores currently equipped equipment
   Equipped = []
#The company's current stats   
   SecArray = [0, 0, 0, 0, 0, 0]

#Called whenever moving something in or out of the currently equipped items.
#Pass the current item's stat array, the stat array, and a + or - symbol
   def arrayedit(array, SecArray, symbol):
        Notify("The stats have changed")
        if symbol == "+":
            SecArray[0] += array[0]
            SecArray[1] += array[1]
            SecArray[2] += array[2]
            SecArray[3] += array[3]
            SecArray[4] += array[4]
            SecArray[5] += array[5]
        if symbol == "-":
            SecArray[0] -= array[0]
            SecArray[1] -= array[1]
            SecArray[2] -= array[2]
            SecArray[3] -= array[3]
            SecArray[4] -= array[4]
            SecArray[5] -= array[5]
        return()

但是，如果“装备”数组中有任何物品，则每次单击文本按钮时，它们的统计信息都会添加到当前统计信息中（例如，如果一个物品的统计信息中有3个，那么玩家的当前统计信息将在每次单击任何按钮时增加3个，无限向上计数）。类似地，如果“装备”数组中有任何物品，则每次单击文本按钮时，都会从玩家的当前属性中减去它们的当前属性。“Items”数组中的项没有任何效果

以下代码适用于windows商店和装备/拆卸设备

除此之外，所使用的数组和函数不会在程序的其他地方调用或引用。我相信每次单击按钮（包括返回按钮）时，都会为装备和设备阵列中的项目调用“arrayedit”功能，但我不确定原因。如有任何见解，将不胜感激
