numpy.ones() in Python

The ones() method of Python numpy class returns a new array of given shape and type, filled with ones.


numpy.ones(shape, dtype=None, order=’C’)


The numpy.ones() method consists of three parameters, which are as follows:

shape : This parameter represents the integer or sequence of integers

order  : The order parameter can be either C_contiguous or F_contiguous. C order means that operating row-rise on the array will be slightly quicker

FORTRAN-contiguous order in memory (the first index varies the fastest). F order means that column-wise operations will be faster.

dtype : It is an optional parameter. It depicts the data type of returned array, and by default, it is a float.


This method returns the array of ones having given shape, order and datatype.
