Question

在上面的示例中，创建了一个列表，然后单击 edit 按钮，该列表将处于可编辑模式。

它是使用 angular-xeditable 创建的。

从列表中，只想检查重复项，如果匹配则显示错误消息。

以下代码能够找到重复项并显示错误。但是，如果两个或多个值具有相同的名称。发生以下错误。

如果其中任何一个完成更改，则错误的其他值消息保持不变。
单击删除按钮（ x ）不会隐藏错误消息。

谢谢。

Answer 1

def FindDuplicates（in_list）：
    唯一=设置（in_list）
    每个都有唯一性：
        count = in_list.count（每个）
        如果计数> 1：
            打印“此列表中有重复项”
            返回True
    打印“此列表中没有重复项”
    返回False

如果名称 =='主要'：

# test it  
a = [8, 64, 16, 32, 4, 24]  
b = [2,2,3,6,78,65,4,4,5]  

FindDuplicates(a)  
FindDuplicates(b)

从列表中检查重复项并显示错误信息
