numpy-zeros, zeros_like

• zeros

 

Returns a new array of given shape and type, filled with zeros.

np.zeros((5,), dtype=int)
>>>
array([0, 0, 0, 0, 0])

---

s = (2,2)
np.zeros(s)
>>>
array([[ 0.,  0.],
       [ 0.,  0.]])

 

• zeros_like

 

Return an array of zeros with the same shape and type as a given array.

 

x = np.arange(6)
x = x.reshape((2, 3))
x
>>>
array([[0, 1, 2],
       [3, 4, 5]])
np.zeros_like(x)
array([[0, 0, 0],
       [0, 0, 0]])

 

y = np.arange(3, dtype=float)
y
>>>
array([0., 1., 2.])

np.zeros_like(y)
>>>
array([0.,  0.,  0.])
