Copying Arrays

It's worth noting that NumPy offers various methods for duplicating arrays. In this section, we'll explore one of these methods, namely: .copy().

Note
The .copy() method creates a new array with the data from the original one.

Using the .copy() method:


              123456789
            
import numpy as np

arr = np.array([7, 43, 56, 123, 10, 3])
x = arr.copy()

arr[0] = 42

print(arr)
print(x)

Tarefa

You have the following array: [12, 56, 78, 65, 1, 5].

You have to obtain the following arrays using the correct method: arr_1 = [11, 56, 78, 0, 1, 5] arr_2 = [12, 56, 78, 65, 1, 5]

Replace element 12 with 11, and element 65 with 0.
