从绑定传递列表

Question

学习python的早期阶段，我遇到了问题。我正在建立一个骰子游戏。我希望将dice [0]的值传递给holdDie1函数。我创建的标签准确显示了dice [0]的正确值，但是当我用bind调用该函数将其分配给另一个列表时，我收到一个错误：

第75行，在holdDie1中 keep [0] =骰子[0] TypeError：＆＃39;事件＆＃39; object不支持索引

 public class TenantContext : DbContext
 {
    public TenantContext(string connection, Tenanat tenanat)
        : base(connection)
    {
        //create DB for tenant
        Database.CreateIfNotExists();
        //create user for the new Db
        string sql = "CREATE LOGIN \"" + tenanat.Email + "\" WITH PASSWORD = '" + tenanat.Password + "'; USE " + tenanat.Name + "; CREATE USER \"" + tenanat.Email + "\" FOR LOGIN \"" + tenanat.Email + "\" WITH DEFAULT_SCHEMA = dbo;";
        Database.ExecuteSqlCommand(sql);
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {


        base.OnModelCreating(modelBuilder);
    }

    public DbSet<Product> Products { get; set; }
    public DbSet<Order> Orders { get; set; }
   }}
