"""Interactive widgets for the Jupyter notebook.
|
|
|
|
Provide simple interactive controls in the notebook.
|
|
Each Widget corresponds to an object in Python and Javascript,
|
|
with controls on the page.
|
|
|
|
To put a Widget on the page, you can display it with Jupyter's display machinery::
|
|
|
|
from ipywidgets import IntSlider
|
|
slider = IntSlider(min=1, max=10)
|
|
display(slider)
|
|
|
|
Moving the slider will change the value. Most Widgets have a current value,
|
|
accessible as a `value` attribute.
|
