How to use _on_service_worker method in Playwright Python

You can assign to a variable defined in an outer scope by declaring that it's a nonlocal variable:

from playwright.sync_api import sync_playwright

def new_cookie(url):
    cookie = None
    def set_cookie(req):
        nonlocal cookie
        if "cookie" in req.headers:
            cookie = req.headers["cookie"]

    with sync_playwright() as p:
        browser = p.firefox.launch()
        page = browser.new_page()
        page.on("request", set_cookie)
        page.goto(url)
        browser.close()

    return cookie

print(new_cookie("https://example.com"))

Methods in python are snake case. context.add_cookies should do the work.

If you want a Playwright image with Python instead of the Playwright image with Node you have currently set,

do

FROM mcr.microsoft.com/playwright/python:v1.23.0-focal

instead. You won't then need to install python3-pip (or playwright!) at all.

Additionally, you'll probably want to explicitly spell out python3 instead of python:

FROM mcr.microsoft.com/playwright/python:v1.23.0-focal
RUN pip3 install TikTokApi
RUN playwright install
COPY . .

Maybe you can check the selector is visible and then you can click it?

if PageMethod("isVisible","#selector1"):
    PageMethod("click","#selector1")    
if PageMethod("isVisible","#selector2"):
    PageMethod("click","#selector2")    
if PageMethod("isVisible","#selector3"):
    PageMethod("click","#selector3")

I think you can usue the method isVisible, because scrapy_playwright support the same you have in playwright: https://github.com/scrapy-plugins/scrapy-playwright#supported-methods

And of course, isVisible() is a supported method in playwrgiht: https://playwright.dev/python/docs/api/class-page#page-is-visible

Use a for loop to iterate over dictionary contained in cookies and check if it contains name which has value equal to "auth_token" or not, if it does then access the "value" key of that dictionary.

with open('t.json') as f:
    content = json.load(f)
    cookies = content['cookies']
    
    for data in cookies:
        if data['name'] == 'auth_token':
            auth_token = data['value']
    
    print(auth_token)

Referencing this:

1. pip install --upgrade pip
   

2. pip uninstall playwright
   

3. pip install playwright
   

4. Change to your script directory

5. playwright install
   

You could use something called element_handle.is_visible() from here.

your code should look something like below.

href_element = page.query_selector("a")
href_element.is_visible()

Functions assigned to events (in any module) can't return value and you may need to use global variable for this. But lambda can't use global and can't assign value to variable so it needs normal function

url = ""

def on_response(response):
    global url  # inform functio to use external variable (instead of local variable) when you use `=` to assign value
    
    if ".m3u8" in response.url:
        url = response.url

page.on("response", on_response) 

Looks like you just didn't download the file that was included in the tutorial, by the location of /usr/lib/chromium-browser/chromedriver. We can't really help you here, you just have to download the chromedriver.

I would recommend you use python playwright instead of selenium, as it is just a more modern library, with a slightly smaller learning curve, in my opinion, but that's just a recommendation.
