Tool for formatting inputs for selenium css selectors for multi class names (with spaces) - selenium python

Image
When you use selenium to select an element with multiple classes using driver.find_element_by_css_selector(), you need to replace spaces with dot notation. For example, To select The following element:  <i align="center" class="far fa-copy croc-copy-icon">  you 'll need to use the following selector with dot notation formatting: driver.find_element_by_css_selector(".far.fa-copy.croc-copy-icon”) Having to replace spaces with full stops over and over again can get repetitive and time-consuming especially for lengthy classes. Here is a quick script I use to replace all spaces with dots, and add a dot at the beginning of the string. I found this can save quite a bit of time import pyperclip text = "a really long multi class element t-14 t-black--

Infinite scroll selenium python

Image
One way to handle infinite scroll is by using the height of the viewport. Here we continue to scroll until the viewport height before and after does not change, hence, all elements on the page have been loaded import time def scroll_infinite(driver, wait_time, number_of_times_to_scroll): # Current scroll height current_height = driver.execute_script("return document.body.scrollHeight") while True and number_of_times_to_scroll > 0: # Scroll to bottom of page driver.execute_script("window.scrollTo(0, document.body.scrollHeight);") # Wait for new content to load time.sleep(wait_time) # Calculate new scroll height n_height = driver.execute_script("return document.body.scrollHeight") if n_height == current_height: break number_of_times_to_scroll -= 1 current_height
