import panel as pn

pn.extension()

The Str pane allows rendering arbitrary text in a panel.

Unlike Markdown and HTML panes, a Str pane is interpreted as a raw string without applying any markup and is displayed in a fixed-width font by default.

The pane will render any text, and if given an object will display the object’s Python str representation.

Parameters:#

For details on other options for customizing the component see the layout and styling how-to guides.

enable_streaming (boolean, default=False): Whether to enable streaming of text updates. When enabled, each update to object is diffed against the previous value and only the changed portion is sent to the frontend.
object (str or object): The string to display. If a non-string type is supplied, the str of that object is displayed.

str_pane = pn.pane.Str(
    'This is a raw string which will not be formatted in any way except for the applied style.',
    styles={'font-size': '12pt'}
)

str_pane

Like other panes the Str pane can be updated by setting its object parameter. As mentioned above, non-string types are automatically cast to a string:

str_pane.object = 1.3234232

Since the text is rendered in a <pre> block, whitespace and line breaks are preserved, which makes the Str pane well suited for displaying logs or the output of other Python objects:

import numpy as np

pn.pane.Str(np.random.default_rng(42).random((4, 3)).round(3))
