Apprendre Arrays Operations | Introduction to NumPy

NumPy arrays not only perform faster, but also support different operations, that are not available for built-in lists.

For example, you can add/subtract/multiply/divide by a certain number all the array elements. Or you can multiply two arrays element-by-element.


              123456789
            
# Import the library
import numpy as np
# Creating two arrays
arr1 = np.array([1, 2, 3])
arr2 = np.array([10, 20, 30])

# Perform some arrays operations
print(arr1 + 3)
print(arr1 * arr2)

Tout était clair ?
