1# Basic syntax:
2np.ones((number_rows, number_cols), dtype=int)

4# Example usage:
5import numpy as np
6np.ones((5, 3), dtype=int)
7array([[1, 1, 1],
8       [1, 1, 1],
9       [1, 1, 1],
10       [1, 1, 1],
11       [1, 1, 1]])

13# Note, use np.zeros to create an array of zeros

1import numpy
2print(numpy.ones((2, 3), dtype=int))
3# creates the array of the shape (2, 3) of value 1 in its each cell
4print(numpy.ones(6, dtype=str) 
5# creates an array of size 6 with values of '1'
