Why tuples unpacking is not working with Selenium WebDriverWait?

How is it possible to unpack tuples with Selenium WebDriverWait?

Why this code is not working?

class Test:

    def __init__(self, driver):
        self.driver = driver
        
    editprofile_button = (By.XPATH, "//android.widget.TextView[@text=\"Edit profile info\"]")
    
    def profile_page_should_be_visible(self):
        wait = WebDriverWait(self.driver,20)
        wait.until(EC.presence_of_element_located(*Test.editprofile_button))
        assert self.driver.find_element(*Test.editprofile_button).is_displayed()

But if I write the function like this, then everything is working with WebdriverWait:

def profile_page_should_be_visible(self):
    wait = WebDriverWait(self.driver,20)
    wait.until(EC.presence_of_element_located((By.XPATH, "//android.widget.TextView[@text=\"Edit profile info\"]")))
    assert self.driver.find_element(*Test.editprofile_button).is_displayed()

presence_of_element_located, as most of the other expected conditions, is locating the WebElement on __call__

class presence_of_element_located(object):
    def __init__(self, locator):
        self.locator = locator

    def __call__(self, driver):
        return _find_element(driver, self.locator)

where self.locator is the tuple.

def _find_element(driver, by):
    try:
        return driver.find_element(*by)
    except NoSuchElementException as e:
        raise e

_find_element is using driver.find_element(*by) where by is the tuple. As you can see, the tuple is already being unpacked internally.

You can use Test.editprofile_button without unpacking it

wait.until(EC.presence_of_element_located(Test.editprofile_button))
