Installing jupyter!

I have told you many times how nice is jupyter, a way to program in python in your browser... that is awesome.

If you have all installed, you write on the command prompt:

ipython notebook

or

jupyter notebook

if not

write:

pip install ipython

then write:

pip install notebook

after this, you could also write:

pip install jupyter

If you want to upgrade to the latest version (if you have it yet)

pip install --upgrade ipython


If all goes right you can start the notebook this way:

ipython notebook

or

jupyter notebook


There are also some cool widgets you can use with jupyter.
To install them and enable them do so:

pip install ipywidgets
jupyter nbextension enable --py --sys-prefix widgetsnbextension

The github page for the extensions:
https://github.com/ipython/ipywidgets

PS: IF YOU WANT TO TRY IT WITHOU INSTALLING IT:

try.jupyter.org

And you're good to go!
