Question

我编写了一个函数来清除对象（在列表中），其评级字段是一个字符串或者其评级为0.这就是我所拥有的：

var str = '[{"id":1,"type":"one","status":"pending","user_id":2},{"id":2,"type":"two","status":"pending","user_id":14},{"id":3,"type":"three","status":"queue","user_id":5},{"id":4,"type":"four","status":"queue","user_id":8 }]';

var array = JSON.parse(str);
var myarray = array.map(function(item) {
  return item.type;
});
console.log(myarray);

然后在我的主要方法中，我有这个：

def removeInvalidPlayers(players):
    for player in players:
        if isinstance(player.rating, str) or player.rating == 0:
            players.remove(player)
    return players

当我运行我的脚本时，我收到此错误：

allPlayers = removeInvalidPlayers(allPlayers)
allPlayers.sort(key = lambda x: x.rating)

我认为我的Traceback (most recent call last): File "SquashScraper.py", line 73, in <module> main() File "SquashScraper.py", line 68, in main allPlayers.sort(key = lambda x: x.rating) TypeError: unorderable types: str() < float()方法会解决这种类型的错误。知道为什么不是/我应该如何修理？

Python：如果某个字段是字符串，则删除对象
