我正在尝试创建一个列表对象，其中包含有关职业高尔夫球手的数据。不同的数据点是高尔夫球手的名字和不同距离的推杆百分比。输入每个播放器对象的所有数据后，我想按名称对对象列表进行排序。这些对象的列表称为PlayerNumber。当我尝试按属性“名称”对PlayerNumber进行排序时。我收到一条错误消息，指出“ int”没有属性，并且我不确定为什么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FYI，我对python来说还比较陌生。

最佳答案
不是将PlayerNumber称为整数，而是将PlayerNumber是整数列表，并且该列表（和整数）中的每个元素都没有sort（）尝试的属性“ name”访问（以便对其进行排序）。
编辑：
详细说明一下，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：operator.attrgetter（“ name”）对PlayerNumber进行排序，这意味着它必须在PlayerNumber的每个元素上调用该函数才能获得其在已排序数组中的排名。这就是为什么您尝试从PlayerNumber中的整数中获取.name属性的原因。
关于python - 'Int'对象没有属性，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/46507804/
