Question

我正在尝试创建一个包含职业高尔夫球手数据的列表对象。不同的数据点是高尔夫球手的名字和不同距离的投注百分比。一旦为每个玩家对象输入了所有数据，我想按名称对这个对象列表进行排序。这些对象的列表称为PlayerNumber。当我尝试按属性'name'对PlayerNumber进行排序时。我得到一个错误，指出'int'没有属性，我不确定为什么PlayerNumber被称为整数而不是列表。

任何帮助将不胜感激。这是代码：

我正在使用Python 3.4 spyder IDE。作为一个FYI，我对python相对较新。

谢谢！

并不是说PlayerNumber被称为整数，而是PlayerNumber是一个整数列表，该列表的每个元素（和整数）都没有属性“name”，这种类型排序（）正试图访问（以便对它们进行排序）。

编辑：

详细说明样本中的倒数第二行：

PlayerNumber.sort（key = operator.attrgetter（“name”））

正在尝试使用比较函数对operatorNumber进行排序：operator.attrgetter（“name”），这意味着它必须在PlayerNumber的每个元素上调用该函数以获得其在排序数组中的排名。这就是为什么你试图从PlayerNumber中的整数中获取.name属性。

'Int'对象没有属性
