Selenium weird behavior, element not clickable when it's there - python

I run a multithread python selenium script which gives me unexpected behavior which I can not understand. So after opening a new browser I try to clear the cache with below code ;
driver.get('chrome://settings/clearBrowserData')
WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.XPATH, '//settings-ui')))
driver.find_element_by_xpath('//settings-ui').send_keys(Keys.ENTER)
90 out of 100 times this works but sometimes it throws me this error :
element not interactable
To my understanding somehow the page is not loaded fully and selenium is too "fast".
However I do wait until the element is visible which would eliminate this plus to my understanding the driver.get also waits until the "full get" is returned and finished.
Can someone explain me why this behavior occurs ?
Sub question would be is my understanding right driver.get(page) waits for full page loading done ?

The ElementNotInteractableException exception can occur for a few reasons:
The element that you want to interact with is disabled.
There's an overlay element covering the one you want to interact with, such as a loading spinner.
If it's 1, use EC.element_to_be_clickable instead of EC.visibility_of_element_located.
If it's 2, you'll need to either wait for the overlay element to go away on it's own. Or, perform an action to make the overlay element go away.

How to use selenium to navigate web pages with multiple drop downs and check boxes

I am trying to automate a process to download data from a website. The code works if I run it step by step but if I run it all at once it fails. Giving the error
ElementNotInteractableException: Message: element not interactable
I have got around this using time.sleep(x amount of time) but it still seems to fail intermittently. I am having trouble implementing implicit waits. Any help would be appreciated. Code below.
import selenium
browser = webdriver.Chrome(executable_path=r'path\to\chromedriver.exe')
browser.get("https://map.sarig.sa.gov.au/")
browser.maximize_window()
browser.switch_to.frame(browser.find_element_by_id('MapViewer'))
browser.find_element_by_xpath('//*[#id="TourWidget"]/div[1]/span').click()
browser.find_element_by_xpath('//*[#id="menuAllMapLayers"]/div[2]/p').click()
browser.find_element_by_xpath('//*[#id="238"]/li[1]/div/div/span[1]').click()
time.sleep(3)
browser.find_element_by_xpath('//*[#id="238"]/li[1]/div/div/span[1]').click()
browser.find_element_by_xpath('//*[#id="238"]/li[3]/div/div/label/span').click()
browser.find_element_by_xpath('//*[#id="239"]/li[1]/div/div/span[1]').click()
browser.find_element_by_xpath('//*[#id="239"]/li[3]/div/div/label/span').click()
browser.find_element_by_xpath('//*[#id="menuActiveLayers"]').click()
browser.find_element_by_xpath('//*[#id="groupOptions238"]/span').click()
time.sleep(3)
browser.find_element_by_xpath('//*[#id="238"]/li[2]/div/div[3]/div[2]/span').click()
browser.find_element_by_xpath('//*[#id="groupOptions239"]/span').click()
time.sleep(3)
browser.find_element_by_xpath('//*[#id="239"]/li[2]/div/div[3]/div[2]/span').click()
Use ActionChains and get access to pause(3) instead of using sleep(3) but it could also help to use Waits and checking if your elements actually are "visible" rather than "present" (see expected_conditions)
It's a lot of dropdowns so maybe there are not visible all the time, but you can run these checks after doing a move_to_element() so it would actually be present.

Waiting for elements to become interactible reliably

I'm a noob and trying to automate some online form filling in a certain site. My problem is that some buttons need some time before clicking them, otherwise they don't work (but no error!, execution continues).
My only solution so far is to add a time.sleep(6) before these buttons but this is not ideal.
I am trying to find a better solution.
So far, I have this function:
def Send_Click_dk(bywhat,what):
WebDriverWait(browser, 10).until(EC.presence_of_element_located((bywhat,what)))
WebDriverWait(browser, 10).until(EC.visibility_of(browser.find_element(bywhat, what)))
WebDriverWait(browser, 10).until(EC.element_to_be_clickable(browser.find_element(bywhat, what)))
browser.find_element(bywhat, what).click()
Send_Click_dk(By.NAME, "mainpanel_parentSection_1b0a0b")
First of all, is this a good approach? Am I misunderstanding something?
Secondly, if this is the right approach, what else could I check before clicking the button? So far, all of these checks pass instantly and the .click() is executed but doesn't produce the expected result. Only by adding time.sleep(6) the clicking works as intended.
This is a snapshot of that particular part of the page, I'm having trouble copying the raw text.
The first marked button reveals the second marked button. But if without the time.sleep(x) it just stays closed without revealing the second one.
Many thanks in advance for any help! Cheers!
You definitely can reduce all your code to a single line of
def Send_Click_dk(bywhat,what):
WebDriverWait(browser, 10).until(EC.element_to_be_clickable(browser.find_element(bywhat, what))).click()
Send_Click_dk(By.NAME, "mainpanel_parentSection_1b0a0b")
visibility_of expected condition includes presence_of_element_located since element can't be visible without being present.
element_to_be_clickable internally includes visibility_of.
Also WebDriverWait(browser, 10).until(EC.element_to_be_clickable(browser.find_element(bywhat, what))) returns web element object, so you can click it directly.
Also, make sure the mainpanel_parentSection_1b0a0b name attribute is a fixed value. 1b0a0b suffix seems to be dynamically generated

element click intercepted exception in selenium python

I am a beginner in selenium and having a tough time understanding one of the errors appearing while using selenium chromedriver in python.
So, I am trying to click an element inside an svg tag by using css_selector. But I am getting ElementClickInterceptedException with the error (... is not clickable at point (1281, 60). Other element would receive the click:...). However, if I am putting time.sleep(5) before clicking the element, then I am able to click it. Why is it happening?
My first guess was maybe the element is not becoming visible or is inside an invisible box and I have to wait. Hence I tried to handle it with the explicit wait. But both cases timed out. So I assumed, it was not due to that. But then it is difficult for me to guess the reason, as time.sleep(5) is working.
Thank you in advance.

presence_of_element_located() not working as intended

I use python/selenium for web-scraping and automation through Chrome. Recently I've come across a problem where some pages or websites would load endlessly as a means to prevent bots from scraping them (It often starts to happen after first time). I had no idea how to counter this until I came across the function in question:
wait = WebDriverWait(self.driver, 3)
element = wait.until(
EC.presence_of_element_located((By.XPATH, '//button[.="Sign up"]'))
)
The way I understood this function is that it sat a timeout for the page (3 seconds in this example) and at the same time checking whether an element has been loaded into the page or not. If the element has been loaded or if the wait times out, the program stops waiting for the page to load and continues on with the next line of code, which is, in my case, a print("timeout") function.
Thing is, as I use the function as demonstrated above the program still waits for the page to load, as "timeout" only appears in the console after I manually stop the page loading from the browser.
I am sure the element is present in the page (and quite visible) as it continues to load endlessly, because once I press the X button and stop the page loading, "timeout" is printed and the element is interacted with successfully.
I also tried EC.visibility_of_element_locatedto the same effect.
What is going wrong and how do I achieve the functionality I need?
Since you didn't share a link to the page you are working on I can only guess.
So my guess is: you are using a wrong locator.
Try using this
wait = WebDriverWait(self.driver, 3)
element = wait.until(EC.presence_of_element_located((By.XPATH, '//button[contains(.,"Sign up")]')))
Or this
wait = WebDriverWait(self.driver, 3)
element = wait.until(EC.presence_of_element_located((By.XPATH, '//button[contains(.,"sign up")]')))

How to handle errors (unable to locate element) in Selenium

I am writting bot using Selenium for a game where is a lot of clicking.
Sometimes it shows error Unable to locate element:
selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: /html/body/div/div[1]/header/div/div[1]/a
I have correct Xpath but sometimes it gives me an error in different parts in my code. It is not that I have one mistake and it always show error in one place. My problem is that those errors are random. I am handling it like this:
try:
secondPhoto = self.driver.find_element_by_xpath(
'/html/body/span/section/main/article/div[2]/div/div[1]/div[1]')
secondPhotoOpen = ActionChains(self.driver)
secondPhotoOpen.move_to_element(secondPhoto)
secondPhotoOpen.click()
secondPhotoOpen.perform()
except:
time.sleep(3)
self.driver.find_element_by_xpath(
'/html/body/span/section/main/article/div[1]/div/div/div[1]/div[2]').click()
This is not a ideal solution. It still shows errors but less frequently.
I am also using time.sleep. Usually errors show up when I am doing something else on internet or I have lags(this is the reason why I am using time.sleep) Now, I have about 50 .click() in my code and for all clicks I am doing try except but still it is not working correctly.
Do you have an effective solution for this? How to write a code that use .click() to be 100% sure it works regardless lags, other
browser activity?
How to wait for full load of next page/image after click() ( I am
using time.sleep)?
You can use WebDriverWait:
btn = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, "element_id")))
btn.click()
this will wait at least 10 seconds, until element will be clickable and only then clicks on it. Also I would recommend to read this. With WebDriverWait you don't have to have hard coded pauses.
