Instalar numpy y matplotlib en Python

 Abrimos una terminal y tecleamos

pip install numpy

pip install matplotlib

En nuestro caso lo hemos instalado en Windows usando la terminal PS (PowerShell).

El comando pip es el instalador de paquetes que habitualmente se utiliza con Python.

Si ya tenemos instalado pip es posible que nos pida que instalemos una actualización en caso de que existe una versión nueva.

Después de actualizar el instalador de paquetes pip podemos consultar la versión que tenemos instalada de pip.

pip --version

También podemos pedir la ayuda de pip.
