In Python, arrays can be handled using built-in data types like a list or with an ‘array’ module. The task is simple: we want to create a Python program that prints out the number of elements present in an array. For this, we will use the built-inlen()function, which returns the...
len(arr4d) )print('The number of elements is', arr4d.size )print('The shape of array is', arr4d.shape )print('The stride of array is', arr4d.strides )print('The type of elements is', arr4d.dtype )

You can check the number of elements of an array with size. 可以使用大小检查数组的元素数。 So in this case, I can type x.size and I find out that I have six elements in my array. 在这个例子中,我可以输入x.size,我发现我的数组中有六个元素。 Notice that you don’t have parentheses ...
