Summary

Starting NumPy is just by importing the modules, usually with the alias np, and then creating an array of lists or tuple. Once the array is formed, you can immediately run a mathematical operation that works on all the elements at once. The following example of use shows how to access elements and total calculations without manual repetition.

Key points

Import NumPy with import NumPy as np command.
Np.array() receives a list or tuple to make an array.
Operations like * and + apply to every element of the array.
The size attribute indicates the total number of elements in an array.
