Where can I configure the browser behavior of Playwright in VSCode?

Just use some condition instead of print method, for example you could check if response contains some key in its json:

def run(playwright):
    chromium = playwright.chromium
    browser = chromium.launch()
    page = browser.new_page()
    # Subscribe to "request" and "response" events.
    page.on("request", lambda request: print(">>", request.method, request.url))
    page.on("response", lambda response: print("<<", response.status, response.url))
    page.goto("https://example.com")
    browser.close()

For Example:

page.on("response", lambda response: response if key in response.body())

There should be waitForResponse for python too, and you could use that.

The accepted answer does not work with the newer versions of Playwright. (Thanks @576i for pointing this out)

Here is the Python code that works with the newer versions (tested with version 1.5):

from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    browser = p.chromium.launch()
    page = browser.new_page()
    page.goto('http://whatsmyuseragent.org/')
    ua = page.query_selector(".user-agent");
    print(ua.inner_html())
    browser.close()

To get only the text, use the inner_text() function.

print(ua.inner_text())

https://stackoverflow.com/questions/64303326/using-playwright-for-python-how-do-i-select-or-find-an-element

so you could put something along the lines of hash here:

    src = pkgs.python38Packages.fetchPypi {
      inherit pname version;
      data_sha256 = "sha256:<yourhash>"
    };

while building your pkgs, so that it's defined explicitly (rn, its parsing it as '' as evident in the op)

Not sure about Colab, but in a normal Jupyter notebook you do:

import nest_asyncio
nest_asyncio.apply()

Install with pip install nest-asyncio, and then you can run async stuff in a notebook.

Edit: You are also trying to run a GUI instance of Chrome, with that headless=False - change that to headless=True, Colab doens't run with a GUI.

https://stackoverflow.com/questions/73084593/running-playwright-on-google-colab-gives-error-asyncio-run-cannot-be-called

I tried this and it worked (I used an element handler instead of arguments[0]):

selector = page.query_selector('.my-image')
img_base64 = page.evaluate("""(selector_handle) => {
    var cnv = document.createElement('canvas');
    cnv.width = 300; cnv.height = 300;
    cnv.getContext('2d').drawImage(selector_handle, 0, 0);
    return cnv.toDataURL('image/jpeg').substring(22);
}""", selector)
with open(r"image.jpg", 'wb') as f:
    f.write(base64.b64decode(img_base64))
