I'm trying to display the results of a python query in html. I have the following error and I can't find the solution. I leave code. Thank you for your support

I expected it to show the name of a product, its price and the supermarket but i got this error

JsException(PythonError: Traceback (most recent call last): File "/lib/python3.10/site-packages/_pyodide/_base.py", line 429, in eval_code .run(globals, locals) File "/lib/python3.10/site-packages/_pyodide/_base.py", line 300, in run coroutine = eval(self.code, globals, locals) File "", line 1, in ModuleNotFoundError: No module named 'bs4' )

PyScript supports a wide range of modules and libraries that are not part of the standard library.

You can use third-party packages by specifying them in the <py-env> tag.

Try this, hope it will help.
