Create a Numpy array filled with all ones
In this article, we will learn how to create a Numpy array filled with all one, given the shape and type of array.
We can use Numpy.ones() method to do this task. This method takes three parameters, discussed below –

shape : integer or sequence of integers order : C_contiguous or F_contiguous C-contiguous order in memory(last index varies the fastest) C order means that operating row-rise on the array will be slightly quicker FORTRAN-contiguous order in memory (first index varies the fastest). F order means that column-wise operations will be faster. dtype : [optional, float(byDeafult)] Data type of returned array.
Matrix a : [1 1 1] Matrix b : [[1 1 1] [1 1 1] [1 1 1]]
Matrix c : [[ 1. 1. 1.] [ 1. 1. 1.] [ 1. 1. 1.] [ 1. 1. 1.] [ 1. 1. 1.]] Matrix d : [[ 1. 1.] [ 1. 1.] [ 1. 1.] [ 1. 1.] [ 1. 1.]]
