In Python 3.10, you can use the + operator to concatenate two arrays. Here's an example:
arr1 = [1, 2, 3]
arr2 = [4, 5, 6]
concatenated_arr = arr1 + arr2
print(concatenated_arr)
Output:
[1, 2, 3, 4, 5, 6]
In this example, we have two arrays arr1 and arr2. We concatenate them using the + operator and assign the result to a new variable concatenated_arr. Then we print the concatenated array. As you can see, the output is a new array that contains all the elements of arr1 and arr2.
