一、创建Array 1. 使用np.array()由python list创建 C 数组的概念 : 数据类型一致的一个连续的内存空间 python list列表 (C语言说:列表其实就是一个指针数组),列表不要求数据类型一致 numpy的数组:同样是一个【有序】的,【相同数据类型】的集合 [1, 3.14, ‘helloworld’, student] ...
numpy 创建ndarray np.array(some_np_array) clone a nd-array (e.g. a vector, a matrix). np.array(list) 一阶 如果是类似一维数组,则返回向量(1D-array,不存在行、列之分,shape都是(n,)而非(
