How to wait for number of elements to be loaded using Selenium and Python

Question

Let's say I'm selecting with the selector:

//img[@data-blabla]

And I want to wait for 10 elements to be loaded, not just one.

How would this be modified? I'm making a guess with the index [9]

WebDriverWait(browser, 5).until(EC.presence_of_element_located((By.XPATH, '//img[@data-blabla][9]')))

Answer 1

To wait for 10 elements to load you can use the lambda function and you can use either of the following Locator Strategies:

• Using >:

  myLength = 9
  WebDriverWait(browser, 20).until(lambda browser: len(browser.find_elements_by_xpath("//img[@data-blabla]")) > int(myLength))
  

• Using ==:

  myLength = 10
  WebDriverWait(browser, 20).until(lambda browser: len(browser.find_elements_by_xpath("//img[@data-blabla]")) == int(myLength))
