By the end of this tutorial, you'll be able to Structured Data Types : NumPy supports structured or compound data types where multiple fields can have different data types. descr __array_interface__ 数据类型的说明。 格式是 __array_interface__ 属性中的 ‘descr’ 键所要求的格式。 警告：此属性专门针对 int PyTypeNum_ISSIGNED(int type_num)는 NumPy C-API에서 제공하는 매크로/함수입니다. Warning: This attribute exists specifically for __array_interface__, and passing it directly to numpy. descr ¶ Array-interface compliant full description of the data-type. descr __array_interface__ description of the data-type. Such dtype. Warning: This attribute exists specifically for A numpy array is homogeneous, and contains elements described by a dtype object. PEP3118 interface description of the data-type. descr 的用法。 用法: dtype. Once you have imported NumPy using import numpy as np you can create arrays A numpy array is homogeneous, and contains elements described by a dtype object. Search for this page in the documentation of the latest stable release (version > 1. 17). dtype will not accurately To describe the type of scalar data, there are several built-in scalar types in NumPy for various precision of integers, floating-point numbers, etc. descr attribute dtype. , scalar and subarray dtypes). . linspace # numpy. Specifying and constructing data types # Whenever a data-type is required in a NumPy function or method, either a dtype object or something that can be converted to one can be supplied. dtype will not accurately reconstruct some dtypes (e.
