Python的组合数据类型将数据项集合在一起,以便在程序设计时有更多的选项。 组合数据类型 1、序列类型 Python提供了5中内置的序列类型:bytearray、bytes、list、str与tuple,序列类型支持成员关系操作符(in)、大小计算函数(len())、分片([]),并且是可可迭代的。 1.1 元组 元组是个有序序列,包含0个或多个对象引用,...

本文简要介绍 python 语言中 numpy.chararray.getfield 的用法。 用法: chararray.getfield(dtype, offset=0)以特定类型返回给定数组的字段。字段是具有给定数据类型的数组数据的视图。视图中的值由给定类型和当前数组的偏移量(以字节为单位)确定。偏移量需要使视图 dtype 适合数组 dtype;例如,一个 dtype complex128...
