The ArrayInput
widget allows rendering and editing NumPy arrays using a text entry box whose contents are then parsed in Python. In order to avoid issues with large arrays the ArrayInput
defines a max_array_size
, if the array exceeds this size the textual representation will be summarized and editing will be disbaled.
For more information about listening to widget events and laying out widgets refer to the widgets user guide. Alternatively you can learn how to build GUIs by declaring parameters independently of any specific widgets in the param user guide. To express interactivity entirely using Javascript without the need for a Python server take a look at the links user guide.
For layout and styling related parameters see the customization user guide.
max_array_size
(int): Arrays larger than this limit will be allowed in Python but will not be serialized into JavaScript. Although such large arrays will thus not be editable in the widget, such a restriction helps avoid overwhelming the browser and lets other widgets remain usable.value
: Parsed value of the indicated typedisabled
(boolean): Whether the widget is editablename
(str): The title of the widgetplaceholder
(str): A placeholder string displayed when no value is enteredarray_input = pn.widgets.ArrayInput(name='Array Input ', value=np.random.randint(0, 10, (10, 2)))
array_input
ArrayInput.value
returns a value of the evaluated type that can be read out and set like other widgets:
array_input.value
The ArrayInput
widget exposes a number of options which can be changed from both Python and Javascript. Try out the effect of these parameters interactively:
pn.Row(array_input.controls(jslink=True), array_input)
