I have running a Flask Application with embedded Dash App. The application code is entirely written in python that renders html code. Now, I'd like to be able to export certain <html> elements to pdf.

python code for generating html:

import dash
from dash.dependencies import Input, Output, State
from dash import dcc
from dash import html, dash_table
import dash_bootstrap_components as dbc

html.Div(
    [
        dbc.Row(
            [
                dbc.Card(
                    [
                        dbc.CardHeader("Median"),
                        dbc.CardBody(
                            [
                                html.P(id="card"),
                            ]
                        ),
                    ],
                    id="stat",
                    color="light",
                ),
            ]
        )
    ]
)

Here's the html generated by python code:

<div class="row">
    
  <div id="stat" class="card bg-light">
    <div class="card-header">Median</div>
  </div>
    
  <div class="card-body">
    <p id="card"></p>
  </div>
    
</div>

Is there a pythonic way of exporting html to pdf? I can also write Javascript if there is a way.
