how to check whether the element exists or not in pages-CodePudding

My work is use selenium.webdriver class to click the button in pages with python. If I am trying to find a element in page by xpath,sometimes the element may not exist.So before i use the element I should check whether the element exists or not. The most popular way to solve this question is to use try...expect statement. like this

    def ElementExists(xpath):
   try:
      driver.find_element("xpath",xpath)
      return True
   except:
      return False

It works well. But i find the time cost in try...expect statement is so long. It will cost almost 15 seconds, so what can we do to reduce the time cost with another way? Thanks

A potentially faster alternative would get rid of the try and catch construction:

def ElementExists(xpath):
    e = driver.find_element_by_xpath('xpath')
    if e:
        return True
    return False

Instead of driver.find_element with try-except block you can simply use driver.find_elements method.
Something like this:

def ElementExists(xpath):
    driver.find_elements(By.XPATH, your_xpath)

driver.find_elements will return you a list of web elements matching the passed locator. In case such elements found it will return non-empty list interpreted by Python as a Boolean True while if no matches found it will give you an empty list interpreted by Python as a Boolean False
