Python Selenium: Unable to find xpath to click on element within iframe

I'm using this code but the can't get it to work with the xpath:
browser = webdriver.Chrome(chrome_path)
browser.get("https://planetradio.co.uk/cool-fm")
time.sleep(5)
browser.find_element_by_xpath('//*[#id="notice"]/div[4]/button[2]').click()

The element ACCEPT ALL is within an <iframe> so you have to:
Induce WebDriverWait for the desired frame to be available and switch to it.
Induce WebDriverWait for the desired element to be clickable.
You can use either of the following Locator Strategies:
Using CSS_SELECTOR:
driver.get('https://planetradio.co.uk/cool-fm/')
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[title='SP Consent Message']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button[title='ACCEPT ALL']"))).click()
Using XPATH:
driver.get('https://planetradio.co.uk/cool-fm/')
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[#title='SP Consent Message']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[#title='ACCEPT ALL']"))).click()
Note : You have to add the following imports :
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

Python Selenium get "sold items" information from eBay Productpage

I want to click on the following element "23 verkauft" on an eBay productpage you can see it on this screenshot:
Here is the HTMl Code of this Element:
Here is my Code but the webdriver cant locate the element or can't click on it.
sold = WebDriverWait(driver, 10).until(
EC.presence_of_element_located((By.XPATH, "//span[#class, 'vi-txt-underline']")))
sold.click()

You were close enough. But you have to make to adjustments:
Instead of (By.XPATH, "//span[#class, 'vi-txt-underline']") you need to use (By.XPATH, "//span[#class='vi-txt-underline']")
Instead of presence_of_element_located() you need to use element_to_be_clickable()
Solution
To click on the element with text as 23 verkauft you need to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following Locator Strategies:
Using LINK_TEXT:
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.LINK_TEXT, "23 verkauft"))).click()
Using CSS_SELECTOR:
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a.vi-txt-underline"))).click()
Using XPATH:
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[text()='23 verkauft']"))).click()
Note: You have to add the following imports :
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

You have an error with your locator.
Instead of
//span[#class, 'vi-txt-underline']
It should be
//a[#class='vi-txt-underline']
Also instead of presence_of_element_located you should use visibility_of_element_located since the former method will wait for more mature element state, not only presented on the page but also visible.
Also you can click on the element there directly, no need for the additional code line.
So your code could be
WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.XPATH, "//a[#class='vi-txt-underline']"))).click()

document.querySelector( ).click(); not working selenium $0.click(); undefined

I am trying to click a button with selenium. I have tried Chrome and Firefox console with $0.click(); and works but when testing with the selector it does not work, "undefined", document.querySelector("#td").click();.
I trying with selenium does not work.
HTML:
<td id="td" onclick="if(top.body) Len('td')" class="lenDesActiv">Date</td>
I tried the following:
driver.execute_script('document.querySelector("td#tdDos.lenguetaActiva").click();')
driver.execute_script('document.querySelector("td#").click();')
driver.execute_script('document.querySelector("#td").click();')
driver.execute_script('document.querySelector("td#td").click();')
driver.execute_script('document.getElementById("td").click();')
driver.findElement(By.id("td")).click();
document.getElementById("td").addEventListener("click", function(){
alert("hello world");
});
loginelement = driver.find_element(By.ID, 'td')
driver.execute_script("arguments[0].click();", loginelement)

The WebElement with text as Fecha is within a <frame> so you have to:
Induce WebDriverWait for the desired frame to be available and switch to it.
Induce WebDriverWait for the desired element to be clickable.
You can use either of the following Locator Strategies:
Using CSS_SELECTOR:
driver.get('https://your_website.com/')
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"frame[name='body']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "td#tdDos.lenguetaDesActiva"))).click()
Using XPATH:
driver.get('https://your_website.com/')
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//frame[#name='body']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//td[#id='tdDos' and #class='lenguetaDesActiva']"))).click()
Note : You have to add the following imports :
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

Ways to deal with #document under iframe
Switch to an iframe through Selenium and python

Your issue was an iframe switch to it first.
driver.get("https://webpage.com")
driver.switch_to.frame(driver.find_element_by_xpath("/html/frameset/frameset/frame[2]"))
loginelement = driver.find_element(By.ID, 'td')
driver.execute_script("arguments[0].click();", loginelement)

Try this.
First switch to the frame.
driver.switch_to.frame("body")
wait for the element to be clickable.
WebDriverWait(driver,20).until(EC.element_to_be_clickable((By.XPATH, '//td[#id="td"]')))
Click on element using JavaScriptExecutor.
driver.execute_script('document.querySelector("td").click()')

Python Selenium: How to wait until href attribute contains a specific string?

For example, I'm opening page https://example.com/page-1/ in Selenium, looking for a specific link that contains domain.com. Right now I'm using sleep(20) to ensure the page has fully loaded. But I wonder if I can use WebDriverWait not only for tag presence but also for its contains presence as well. Could not find any solution yet...

You can try something like this, I'm assuming that you are using Firefox but the logic is the same:
firefox = webdriver.Firefox()
firefox.get('https://example.com/page-1/')
#wait for a maximum of 60 seconds in this example
wait = WebDriverWait(firefox, 60)
domain = "domain.com"
wait.until(lambda x: x.find_element_by_css_selector(f"a[href*='{domain}']"))

To wait for the WebElement for the href attribute to contain a specific string, you can induce WebDriverWait for the visibility_of_element_located() and you can use either of the following Locator Strategies:
Full match of domain.com:
Using CSS_SELECTOR:
element = WebDriverWait(browser, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "a[href='domain.com']")))
Using XPATH:
element = WebDriverWait(browser, 20).until(EC.visibility_of_element_located((By.XPATH, "//a[#href='domain.com']")))
Partial match of domain.com:
Using CSS_SELECTOR:
element = WebDriverWait(browser, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "a[href*='domain.com']")))
Using XPATH:
element = WebDriverWait(browser, 20).until(EC.visibility_of_element_located((By.XPATH, "//a[contains(#href, 'domain.com')]")))
Note : You have to add the following imports :
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

Python/Selenium Click on an element in a ul

I am new to Python/Selenium (< 3 days). I am trying to click on the "grades" item of an unordered list (Please see image). I have tried find_element_by_link_text, find_element_by_css_selector but am unable to find it.
Image from inspect element
Thanks.

As per the HTML it is pretty clear that the desired field is within an <iframe> so you have to:
Induce WebDriverWait for the desired frame to be available and switch to it.
Induce WebDriverWait for the desired element to be clickable.
You can use either of the following Locator Strategies:
Using CSS_SELECTOR:
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.ID,"frameDetail")))
element = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a#grades")))
Using XPATH:
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.ID,"frameDetail")))
element = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[#id='grades']")))
Note : You have to add the following imports :
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
