need at least one array to concatenate

Sure! Here's an example of concatenating two arrays in Python:

array1 = [1, 2, 3]
array2 = [4, 5, 6]

concatenated_array = array1 + array2

print(concatenated_array)

Output:

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

In this example, we have two arrays array1 and array2. The + operator is used to concatenate the two arrays into a new array called concatenated_array. The resulting array contains all the elements from array1 followed by all the elements from array2.
