In java selenium-webdriver package, there is a FluentWait class:
Each FluentWait instance defines the maximum amount of time to wait for a condition, as well as the frequency with which to check the condition. Furthermore, the user may configure the wait to ignore specific types of exceptions whilst waiting, such as NoSuchElementExceptions when searching for an element on the page.
In other words, it is something more than implicit and explicit wait, gives you more control for waiting for an element. It can be very handy and definitely has use cases.
Is there anything similar in python selenium package, or should I implement it myself?
(I've looked through documentation for Waits - nothing there).
I believe you can do this with Python, however it isn't packaged as simply as a FluentWait class. Some of this was covered in the documentation you provided by not extensively.
The WebDriverWait class has optional arguments for timeout, poll_frequency, and ignored_exceptions. So you could supply it there. Then combine it with an Expected Condition to wait for elements for appear, be clickable, etc... Here is an example:
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import *
driver = webdriver.Firefox()
# Load some webpage
wait = WebDriverWait(driver, 10, poll_frequency=1, ignored_exceptions=[ElementNotVisibleException, ElementNotSelectableException])
element = wait.until(EC.element_to_be_clickable((By.XPATH, "//div")))
Obviously you can combine the wait/element into one statement but I figured this way you can see where this is implemented.
