numpy.ones () in Python



numpy.ones (shape, dtype = None, order = & # 39; C & # 39;): return a new array of the given shape and type with ones. 
Parameters :

  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. 

Returns :

 ndarray of ones having given shape, order and datatype.

import numpy as geek

 

b = geek. ones ( 2 , dtype = int )

print ( "Matrix b:" , b)

 

a = geek.ones ([ 2 , 2 ], dtype = int )

print ( "Matrix a:" , a)

 

c = geek. ones ([ 3 , 3 ])

print ( "Matrix c:" , c)

Output:

 Matrix b: [1 1] Matrix a: [[1 1] [1 1]] Matrix c: [[ 1. 1. 1.] [1. 1. 1.] [1. 1. 1.]]
