ipywidgets: interactive Jupyter computing

[Jay Wang]

We will be using interactive widgets with sliders, buttons etc.
First install and enable ipywidgets with these terminal commands:

• On Anaconda:
  conda install -c conda-forge ipywidget
  
• On DIY install (path=your scripts path)
  
/path/pip install ipywidgets
/path/jupyter nbextension enable --py --sys-prefix widgetsnbextension
• On the remote Jupyter server:
pip3 install ipywidgets
jupyter nbextension enable --py widgetsnbextension

Once installed and enabled, test with the following in Jupyter

from ipywidgets import interactive
def prtx(x):
    print (x)
interactive(prtx, x=(0,1,.01))
