Here, we will understand the difference between Python List and Python Numpy array....

In this article, we will cover how to normalize a NumPy array so the values range exactly between 0 and 1....

numpy.fromstring() function create a new one-dimensional array initialized from text data in a string....

With the help of dirichlet() method, we can get the random samples from dirichlet distribution and return the numpy array of some random samples by using this method....

In this article, we will be looking at the various approaches to perform Multivariate Normality Tests in Python....

Let’s see the program for getting all 2D diagonals of a 3D NumPy array. So, for this we are using numpy.diagonal() function of NumPy library. This function return specified diagonals from an n-dimensional array....

NumPy builds on (and is a successor to) the successful Numeric array object. Its goal is to create the corner-stone for a useful environment for scientific computing. NumPy provides two fundamental objects: an N-dimensional array object (ndarray) and a universal function object (ufunc). In this post we are going to discuss ways in which we can find the length of each string element in the given numpy array. Problem #1 : Given a numpy array whose underlying data is of string type. Find the length of each element in the given object. Solution : We are going to use numpy.vectorize() function to find the length of each element in the given numpy array object....

In the numpy.core.defchararray.partition() function,  each element in arr, split the element as the first occurrence of sep, and return 3 strings containing the part before the separator, the separator itself, and the part after the separator.  If the separator is not found, return 3 strings containing the string itself, followed by two empty strings....

numpy.exp(array, out = None, where = True, casting = ‘same_kind’, order = ‘K’, dtype = None) : This mathematical function helps user to calculate exponential of all the elements in the input array. Parameters :...

numpy.arcsin(x[, out]) = ufunc ‘arcsin’) : This mathematical function helps user to calculate inverse sine for all x(being the array elements)....

In numpy, arrays may have a data-types containing fields, analogous to columns in a spreadsheet. An example is [(a, int), (b, float)], where each entry in the array is a pair of (int, float). Normally, these attributes are accessed using dictionary lookups such as arr[‘a’] and arr[‘b’]. Record arrays allow the fields to be accessed as members of the array, using arr.a and arr.b. numpy.recarray.flatten() function returns record arrays in one dimension....
