array.ArrayType 已过时的别名array。 数组对象支持索引,切片,连接和乘法的普通序列操作。使用切片分配时,分配的值必须是具有相同类型代码的数组对象; 在所有其他情况下,都会TypeError被提出。数组对象也实现了缓冲区接口,并且可以在任何支持缓冲区对象的地方使用。 以下数据项和方法也受支持: array.typecode 用于创建数
In PostgreSQL, we can create a column as variable-length multidimensional array. It can be of any valid datatype including built-in or user-defined data type. Every data type can have its own array type, for example, an integer has an integer[] array type, varchar has a varchar[] array...
data_type array_id [ index_type ]; data_type是数组元素的数据类型。 array_id是要声明的数组的名称。 index_type是要用作索引的数据类型。 Queues 队列是大小可变的有序元素的集合。队列中的每个元素都由一个序号表示,该序号表示其在队列中的位置,0表示第一个,$表示最后一个。 队列类似于自动增长和收缩的...
Visual Basic for Applications (VBA).In VBA, users can define UDTs by using the type statement. These UDTs might contain a previously defined UDT, an array or multiple elements of a specific data type. The range of each data element is always the same as the range of its data type. In ...

These sampled cells are waypoints (multiple per cell type) that define clear structure in the neighbor graph; however, the cell states themselves remain somewhat diffuse (Fig. 1f). To refine metacells, we employ kernel archetypal analysis (Fig. 1g, Extended Data Fig. 1a and Methods). ...
