An array's properties are critical to determining the shape, dimension of the array, item size, etc. If related to the numpy ndarray object, we can learn more about these in depth. Let's examine a few of these qualities along with the corresponding instances.
Now that we are knowledgeable about multidimensional arrays, we will examine techniques for programmatically examining an array's characteristics (e.g., its dimensionality). It is crucial to comprehend an array's " shape".
To establish the setting for our tutorial, we'll start by creating a basic numpy array.
[[[2 4 7 8] [2 5 8 6]] [[3 8 6 4] [8 6 4 9]] [[2 9 6 8] [6 7 2 9]]]
The previous code indicates that it is a 3D array constructed this way.
This property returns the array's dimension. The size of the NumPy array is indicated as a tuple of integer values. For instance, a matrix with n number of rows and m number of columns will have the shape of the form (n * m).
[[[2 4 7 8] [2 5 8 6]] [[3 8 6 4] [8 6 4 9]] [[2 9 6 8] [6 7 2 9]]] The shape of the array: (3, 2, 4)
We can change the shape of any numpy array by rearranging the shape tuple.
The shape of the original array is: (3, 2, 4) The new shape of the array is: (2, 2, 6)
This feature makes it easier to determine how many dimensions any given NumPy array has. For instance, the number 1 denotes a 1D numpy array, the number 2 denotes a 2D numpy array, and so forth.
The dimension of the array: 3
This attribute makes it easier to determine the length of the numpy array in bytes of every element of the NumPy array. As an illustration, if your array contains integers, this feature will give 88 as integers and need 88 bits of memory.
The itemsize of the array is: 8
