How to use is_positional_exception method in Playwright Python

You need playwright added to your PATH.

However, a better way to do this (if python is added to your path) without adding it to your PATH is by running:

python -m playwright install

This runs the playwright module as a script. Use python -h for more information on these flags, and python -m playwright for more information on the flags supported specifically by playwright

You do not need to save the image to a file at all (cmp. screenshot documentation), but instead can simply store it in a variable, like img = page.screenshot(). You can then pass that variable to your REST request. I use the requests module in the example below, the POST request is simplified and may require some additional parameters (depending on your API) or for instance different URLs for the different browser types:

from playwright import sync_playwright
import requests

with sync_playwright() as p:
    for browser_type in [p.chromium, p.firefox, p.webkit]:
        browser = browser_type.launch()
        page = browser.newPage()
        page.goto('https://scrapingant.com/')
        # save screenshot to var
        img = page.screenshot() 
        # pass var directly to your request
        files = {'image': img, 'content-type': 'image/png'}
        requests.post('http://yourresturl.com', files=files)
        browser.close()

If you really wanted to save the image to a temporary file for some reason (which, as I understand your use case, is not really necessary), you could e.g. use the tempfile module and create a named temporary file (cmp. How to use tempfile.NamedTemporaryFile()?):

from playwright import sync_playwright
import tempfile
import requests

tf = tempfile.NamedTemporaryFile(suffix='.png')

with sync_playwright() as p:
    for browser_type in [p.chromium, p.firefox, p.webkit]:
        browser = browser_type.launch()
        page = browser.newPage()
        page.goto('https://scrapingant.com/')
        # save screenshot to temporary file
        page.screenshot(path=tf.name)
        # send request loading temporary file
        requests.post('http://myresturl.com', {'media': open(tf.name, 'rb')})
        browser.close()        

# close temporary file
tf.close()

You need to install browsers by doing playwright install or python -m playwright install see here: https://playwright.dev/python/docs/intro#installation

You should be able to get that button by text:

page.locator('"Log in"').click()

The locator will help you find an element. But from there, if you don't have an element to pierce the Shadow DOM, you might need to do that manually.

text = page.locator('some-element').first.evaluate("node => node.shadowRoot.innerHTML")

At the end of each iteration of "y" you issue a mouse up event. However, you dont issue a mouse move event to the start of the new line before putting the mouse down again.

Try the below code:

    for y in range(100, 1000, 100):
        # Generate mouse points
        points = []
        wm(start_point, y, x, y, M_0=15, D_0=12, move_mouse=lambda x, y: points.append([x, y]))

        page.mouse.up()
        # Move mouse to start of new line
        page.mouse.move(points[0][0], points[0][1])
        # Mouse back down
        page.mouse.down()
        #Iterate the remaining points
        for point in points[1:]:
            page.mouse.move(point[0], point[1])
        page.mouse.up()

You could use a regular expression for your locator:

page.locator(text=/\d{1,2}\sseconds?\slater/i)

It looks like there is some kind of lazy load, at first, first 8 elements are loaded, if you scroll down, more content will load
