Python | Numpy ndarray.__array__()

With the help of ndarray.__array__() method, we can create a new array as we want by giving a parameter as dtype and we can get a copy of an array that doesn’t change the data element of original array if we change any element in the new one.

Syntax : ndarray.__array__()

Return :

• Returns either a new reference to self if dtype is not given
• New array of provided data type if dtype is different from the current dtype of the array.

Example #1 :

In this example we can see that we change the dtype of a new array by just using ndarray.__array__() method.

# import the important module in python
import numpy as np

# make an array with numpy
gfg = np.array([1, 2, 3, 4, 5])

# applying ndarray.__array__() method
geeks = gfg.__array__(float)

print(geeks)

Output:

[ 1.  2.  3.  4.  5.]

Example #2 :

# import the important module in python
import numpy as np

# make an array with numpy
gfg = np.array([[1.1, 2, 3.3, 4, 5],
                [6, 5.2, 4, 3, 2.2]])

# applying ndarray.__array__() method
geeks = gfg.__array__(int)

print(geeks)

Output:

[[1 2 3 4 5]
 [6 5 4 3 2]]
