what is mean by w=np.zeros((1,3) ?

  np.zeros() returns an array of a given shape filled with zeros. (Note that we are importing numpy as np)

  Therefore, np.zeros((1,3)) returns a 1x3 matrix filled with zeros. The default datatype of the filled values in the matrix and hence the matrix is numpy.float64.

  Take the following example.

  import numpy as np
  
  w = np.zeros((1,3))
  print(w)
  

  This will give the following output.

  array([[0., 0., 0.]])
