在数据分析过程中,我遇到了一个错误,试图使用shape属性来查看一个列表的维度时,程序抛出了异常: my_list=[1,2,3]print(my_list.shape)# AttributeError: 'list' object has no attribute 'shape' 1. 2. 错误日志分析 以上代码在执行时,Python报错提示我们AttributeError表示列表对象并没有shape属性。这种现象反...

of range 一维情况中array创建的可以看做list(或一维数组),创建时用()和[ ]都可以,多维也一样,两种方法创建后的输出显示结果也相同,这里使用[ ]进行创建输出a的shape会显示一个参数,就是这个list中元素个数创建时也可以直接使用np.zeros([1]),这样会创建全0的list,或者np.ones([1]),不需要我们输入数据,...
