How can one perform multiplication on a one-dimensional array in Python?

edit

You can perform multiplication on a one-dimensional array in Python using the numpy library. Here's an example:

import numpy as np

arr1 = np.array([1, 2, 3])
arr2 = np.array([4, 5, 6])

# Multiply two arrays element-wise
result = arr1 * arr2

print(result) # Output: [ 4 10 18 ]

In the above example, we first import the numpy library and create two one-dimensional arrays arr1 and arr2. To perform multiplication on these arrays, we simply use the * operator, which multiplies the corresponding elements in each array. The resulting array is stored in the variable result and printed to the console.
