Numpy full() to get array of input shape and type filled with input value

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

Return array filled with fill_value of given shape and type.

`shape`	Int, or sequence ( 2,3), shape of the output array
`fill_value`	fill value to be used
`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

Using shape

import numpy as np
ar=np.full((1,3),5)
print(ar) # [[5 5 5]]

Output

[[5 5 5]]

Let us use different value for shape

ar=np.full((3,3),5)
print(ar)

Output

[[5 5 5]
 [5 5 5]
 [5 5 5]]

ar=np.full((4,1),88)
print(ar)

Output

[[88]
 [88]
 [88]
 [88]]

We will try to return string dtype

ar=np.full((3,3),'a',dtype=str)
print(ar)

Output

[['a' 'a' 'a']
 ['a' 'a' 'a']
 ['a' 'a' 'a']]

dtype=float

ar=np.full((1,3),4,dtype=float)
print(ar)

Output

[[4. 4. 4.]]

dtype=int

ar=np.full((1,4),12,dtype=int)
print(ar)

Output

[[12 12 12 12]]
