Numpy ones to get array filled with ones

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

Return ndarray of input shape, filled with ones.

`shape`	Int, or sequence ( 2,3) , the shape of the output
`dtype`	data-type( Optional ), Data Type of returned array.
`order`	{'C','F'} Optional, how the output is to be stored. C- style or Fortan style


Shape: (3, 4) Dimension 2	Shape: (4, 3) Dimension 2

Using shape

dtype

We will try to return string dtype

import numpy as np
my=np.ones(4,dtype=str)
print(my)

Output

['1' '1' '1' '1']

dtype=float

my=np.ones(4,dtype=float)

Output

[1. 1. 1. 1.]

dtype=int

my=np.ones(4,dtype=int)

Output

[1 1 1 1]
