Playwright will work with proprietary Chromium-based browsers (including Opera, Edge, Chrome etc.), you can install the browser independently from Playwright and then pass path to its executable via execuable_path launch option:

browser = playwrights.chromium.launch(executable_path='/opt/path_to_opera_bin')

For automating WebKit and Firefox Playwright currently requires remote debugging protocol which is only available in the custom builds.

https://www.piwheels.org is where wheels for Raspberry Pi are published, not PyPI. This is the list of wheels for "playwright": https://www.piwheels.org/project/playwright/ . Version 0.162.2 is the latest available release (click on "Show more releases").

To install from PyPI try to install from both PyPI and PiWheels:

pip install --index-url=https://pypi.org/simple/ --extra-index-url=https://www.piwheels.org/simple/ playwright

in the docker, you don't need to go inside python. Just run from bash:

$ npx playwright open google.com

You can use the not_be_visible expect assertion for this.

expect('element CSS here').not_to_be_visible()

By default expect assertions have a 5 second timeout, in case you want to increase the timeout, you can do like this:

expect('element CSS here').not_to_be_visible(timeout=7000)

After trying many different variants, I guessed a working syntax

handle.selectOption({"label": "Banana"})

Have you tried using general CSS selector? Unsure why your Xpath selector doesn't work, and assuming there's a specific reason you are using xpaths, but by default I usually use general CSS selectors rather than xpaths if I can. Right click the element and Copy > Selector. From your pic it looks like it will be "#jrhFRM:barFiltro:filtros:cursoPesquisa" Thus

pagina.locator("#jrhFRM:barFiltro:filtros:cursoPesquisa").click()

Hope this works. Also, check that you have copied the correct xpath, as the id in your error message...

"jrhFrm:barFiltro:filtros:nomeDoCurso_hinput"

...does not look like it matches the id in your screenshot...

"#jrhFRM:barFiltro:filtros:cursoPesquisa"

Let us know.

Found my answer ...

open a second asyncio.ensure_future() with a new definition that asks constantly for new values.

async def read_the_values_from_while_loop():
    while True:
        await asyncio.sleep(5)
        x = classname.value
        print(x)


asyncio.ensure_future(open_browser())
asyncio.ensure_future(read_the_values_from_while_loop())
loop.run_forever()
