Can't install jupyter notebooks

After phyton instalation, can’t install jupyter notebooks like shows the add tutorial:

Para usar Jupyter Notebook:

  1. Abre la línea de comandos (Terminal en macOS/Linux o Command Prompt en Windows).
  2. Ejecuta el siguiente comando para instalar Jupyter Notebooks:

pip install jupyter notebooks

  1. Una vez instalado, ejecuta el siguiente comando para iniciar Jupyter Notebook:

jupyter notebooks

Se abrirá una ventana del navegador con la interfaz de Jupyter Notebook.
4. Haz clic en “New” y selecciona “Python 3” para crear un nuevo cuaderno (notebook).

this looks similar to pip: command not found. which can be solved by copying the error message to google, then looking at the results. That’s the nice thing about working with the terminal.
I don’t know whether it’s as reliable with spanish, but you might be able to switch the console language to English if it comes to that.

Regardless, I’d recommend installing from conda: Installing conda — conda 24.7.2.dev41 documentation
That comes with almost everything you’ll need for a long time.

Also there is actually something to the advice on here: I Don't Like Notebooks - Joel Grus - #JupyterCon 2018 - Google Slides
TLDR: Jupyter isn’t actually very good for beginners. I’d recommend starting with spyder. (Which is also included in conda.)
