Here, the input was a simple Python list that contains several letters. Some of the letters were repeated. The output is a Numpy array that contains the unique values that were in the input. In other words, the output array contains the same values, but with all of the duplicates removed...
values 您还可以从渲染器添加或移除值。每个唯一值实际上是对象模型中的项目,并且每个项目都在ItemGroup内关联。对于addValues或removeValues,您需要使用 Python 字典。字典键是组标题的名称,其值是基于fields属性的值列表。还有一个listMissingValues方法,可供您确定渲染器当前缺少哪些值。如果您有意调用removeValues,则...
