Note: The length of an array is always one more than the highest array index. The len() method helps us find out the number of data values present in the NumPy array. By default equal to the length of the array, step is the steps the slicing process would take from start to stop. By default set to 0, stop is the ending index, before which the slicing operation would end. By default set to 1. Use the len() method to return the length of

The NumPy size() function has two arguments. Methods for Array Slicing in Python. a.size returns a standard arbitrary precision Python integer. Equal to np.prod(a.shape), i.e., the product of the array’s dimensions.. Notes. Tutorials, references, and examples are constantly reviewed to avoid errors, but we cannot warrant full correctness of all content. Examples might be simplified to improve reading and learning. Array in Python is no inbuilt data type. Arrays in Python is an altogether different thing. To find python NumPy array size use size() function.
