You can use the addInitScript function.

await page. add_init_script("() => Object.defineProperty(navigator,'webdriver'...");

https://stackoverflow.com/questions/70864734/modifying-navigator-webdriver-flag-to-prevent-playwright-detection

Type F12 in Google Chrome and go to the console.

Write $x() and place the xpath selector inside the parenthesis. Hit the enter key and make sure you actually find the right selector.

No need to use e.value, you can do something like this:

p1 = page.locator("//*[@id='rc-tabs-1-panel-apikey']/div/span/input")
p1text = p1.inner_text

Also - use * as less as possible. If the element with the id is a div write div for example and not *. It makes the searching faster.

for i in range(0, 5):

            html = response.text
            # print(html)
            soup = BeautifulSoup(html, "html.parser")
            search_date = soup.find_all("input")[-6]["value"]
            await page.click(
                "#yDmH0d > c-wiz.zQTmif.SSPGKf > div > div:nth-child(2) > c-wiz > div > c-wiz > div.PSZ8D.EA71Tc > div.Ep1EJd > div > div.rIZzse > div.bgJkKe.K0Tsu > div > div > div.dvO2xc.k0gFV > div > div > div:nth-child(1) > div > div.oSuIZ.YICvqf.kStSsc.ieVaIb > div > div.WViz0c.CKPWLe.U9gnhd.Xbfhhd > button"
            )

            yield {
                "search_date": search_date,
            }

This logic to extract all the dates in the range is incorrect. Understand the flow of

you make request to the flight page.
you get the response.
In parse method you are trying to extract the search date.

search_date = soup.find_all("input")[-6]["value"]

This line is only returning one date and not a list. Moreover, I don't understand the logic behind the for loop here. Because this piece of code is not making any further requests as you are trying to achieve with the extracted dates[mentioned in the question]

Important thing to note here is, you have to got the entire html response in one go. You can now use css selectors or soup to extract all the selected dates. Running the for loop for 5 times, doesn't solve any purpose, as you are executing the same information 5 times.

Use response.css('<<Path to the dates in the select>>').getall() to get all the dates you are looking for. Process the information further.

Improvisation on the logic: You can improvise on the logic, I am not sure why you are extracting range of dates, when you can just extract the departure and return dates for the page. And make a request using them. Or Just extract the departure date and increment it and make another request using that date for further information.

The following is one way to get the images on that page - apparently only 398, not 600+ - it's even specified in the top breadcrumb - Trail Running Shoes(398)). Solution is based on Selenium, you're welcome to functionalize it, OOP it, whatever, I'm only giving you the actual method of obtaining the images.

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys
import time as t

chrome_options = Options()
chrome_options.add_argument("--no-sandbox")
chrome_options.add_argument('disable-notifications')
chrome_options.add_argument("--headless")
chrome_options.add_argument("window-size=1280,1080")

webdriver_service = Service("chromedriver/chromedriver") ## path to where you saved chromedriver binary
browser = webdriver.Chrome(service=webdriver_service, options=chrome_options)
wait = WebDriverWait(browser, 20)
actions = ActionChains(browser)


url = 'https://www.tradeinn.com/runnerinn/en/mens-shoes-trail-running-shoes/10005/s#fq=id_familia=10002&sort=v30_sum;desc@tm10;asc&fe=&pf=id_subfamilia=10005@&start=0'
browser.get(url)
pbody = wait.until(EC.presence_of_element_located((By.TAG_NAME, 'body')))
for x in range(14):
    pbody.send_keys(Keys.PAGE_DOWN)
    print('scrolled')
    t.sleep(1)
t.sleep(5)
images = wait.until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, 'img[class="imagen_buscador"]')))
print(len(images))
for i in images:
    print(i.get_attribute('src'))

Result in terminal:

For Selenium docs, see https://www.selenium.dev/documentation/

https://stackoverflow.com/questions/73799005/scrapy-playwright-scrolldown-and-wait-to-load-the-html

From the docs, you should use a string as selector.

page.waitForSelector(selector[, options])

selector <string> A selector to to query for

page.click(selector[, options])

selector A selector to search for an element

selector = '//*[@id="sections-scroll-target"]/ul/ul/li[8]/a'
    
page.wait_for_selector(selector, timeout=10000)

page.hover(selector)

Looks like you want https://www.testdummysite.com/news/markets?mod=nav_left_section

If so this will work

//*[@href= "https://www.testdummysite.com/news/markets?mod=nav_left_section" ]

but these get a different link https://www.testdummysite.com/?mod=nav_left_section.

//*[@id="sections-scroll-target"]/ul/ul/li[8]/a

#sections-scroll-target > ul > ul > li:nth-child(8) > a

Because these URLs are similar, I wonder if you've posted the HTML accurately?

https://stackoverflow.com/questions/71631162/playwright-python-tab-link-not-visible

You can define your own function like this one:

def my_own_wait_for_selector(page, selector, time_out):
    try:
        page.wait_for_selector(selector, timeout=time_out)
        return True
    except:
        return False

That function will wait for a selector and if given some time (miliseconds) the element is not there it will return False instead of trowing an error.

Then in your code you could try something like:

while not my_own_wait_for_selector(page, "my_button_selector", 5000):
    page.reload()
page.locator("my_button_selector").click()

As you can see we are checking if our button is present, and we will wait only 5 seconds, if after 5 seconds the button is not there, we will reload, and again and again until our button is there, once our button is there code will continue and then we will click the button.

Be careful, because if your button is never there, your script will reload and your script will never finish, so you should add some other condition to your while
