How to suppress Pyodide Warning in PyScript?

Question

I have the following PyScript + HTML example and I get the following error:

/lib/python3.10/site-packages/pyodide/__init__.py:74: FutureWarning: pyodide.create_proxy has been moved to pyodide.ffi.create_proxy Accessing it through the pyodide module is deprecated. warn(

How I can suppress/remove the warning?

Why I get this error even when I use:

from pyodide.ffi import create_proxy

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">

    <link rel="stylesheet" href="https://pyscript.net/latest/pyscript.css" />
<script defer src="https://pyscript.net/latest/pyscript.js"></script>
  </head>
  <body>
    <h1>PyScript - Pyodide Warnning</h1>
    <input id="inp-cheese" type="text" placeholder="Want cheese? y|n">
    <input id="inp-bacon" type="text" placeholder="Want bacon? y|n">
    <input id="inp-mashrooms" type="text" placeholder="Want mashrooms? y|n">
    <input id="inp-paper" type="text" placeholder="Want paper? y|n">
    <button id="btn2" class="button-14" role="button">Go</button>

<py-script> 
from pyodide.ffi import create_proxy
from js import document

def on_btn2_click(event):
    global cheese
    global bacon
    global mashrooms
    global paper
    input_cheese = Element("inp-cheese")
    input_bacon = Element("inp-bacon")
    input_mashrooms = Element("inp-mashrooms")
    input_paper = Element("inp-paper")
    cheese = input_cheese.value
    bacon = input_bacon.value
    mashrooms = input_mashrooms.value
    paper = input_paper.value

button2 = document.querySelector("#btn2")
button2.addEventListener("click", create_proxy(on_btn2_click))
</py-script>

<py-repl id="my-repl-23nov22-0931" auto-generate="true"> 

if cheese == 'y':
    print("+ Cheese")
if bacon == 'y':
    print("+ Bacon")
if mashrooms == 'y':
    print("+ Mashrooms")
if paper == 'y':
    print("+ Paper")
print("_____")
</py-repl>

This issue was fixed in pyscript#867 and the fix should be included in the next release.

Otherwise, you could try to disable all warnings altogether,

import warnings
warnings.filterwarnings("ignore")

but I'm not sure it would be called early enough in the <py-script> tag.

The other solution is to build the latest pyscript version, which includes the fix, and use that.
