numpy.ones_like() in Python

Last Updated : 8 Mar, 2024
The numpy.one_like() function returns an array of given shape and type as a given array, with ones.
Syntax: numpy.ones_like(array, dtype = None, order = 'K', subok = True)
Parameters :
array : array_like input
subok : [optional, boolean]If true, then newly created array will be sub-class of array; 
 otherwise, a base-class array
order : C_contiguous or F_contiguous
 C-contiguous order in memory(last index varies the fastest)
 C order means that operating row-wise 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(byDefault)] Data type of returned array. 
Returns :
ndarray of ones having given shape, order and datatype.
Output:
Original array : 
 [[0 1]
 [2 3]
 [4 5]
 [6 7]
 [8 9]]

Matrix b : 
 [[ 1. 1.]
 [ 1. 1.]
 [ 1. 1.]
 [ 1. 1.]
 [ 1. 1.]]

Matrix c : 
 [1 1 1 1 1 1 1 1]
