python - 我可以制作一个带有值列表的 ipywidget floatslider 吗？

Question

我想做一个ipywidget floatslider，但传递一个值列表，而不是范围和步骤。有没有办法做到这一点，或者让下拉小部件成为唯一的选择？

Woops! You can use SelectionSlider, e.g.:

import ipywidgets as widgets

def test(val):
    print(val)

widgets.interact(test, val=widgets.SelectionSlider(description='value',   options=['1', '50', '300', '7000']))

This widget wasn't available in my ipywidgets 4.0, so I had to upgrade. Also, make sure that afterward you run

jupyter nbextension enable --py --sys-prefix widgetsnbextension

as described in their installation instructions.
