Fetch all href link using selenium in python.
We can fetch href links in a page in Selenium by using the method find_elements(). All the links in the webpage are designed in a html document such that they are enclosed within the anchor tag.To fetch all the elements having tagname, we shall use the method find_elements_by_tag_name(). It will fetch a list of elements of anchor tag name as given in the method argument. If there is no matching tagname in the page, an empty list shall be returned.ExampleCode Implementation.from selenium import webdriver driver = webdriver.Chrome (executable_path="C:\chromedriver.exe") driver.maximize_window() driver.get("https://www.google.com/") # identify elements with tagname lnks=driver.find_elements_by_tag_name("a") # traverse ...

Read MoreTest if element is present using Selenium WebDriver?
We can verify if an element is present using Selenium. This can be determined with the help of findElements() method. It returns the list of elements matching the locator we passed as an argument to that method.In case there is no matching element, an empty list [having size = 0] will be returned. We are not using the findElement() method since if there is no matching element, this method gives NoSuchElementException.In an event of any exception, we have to handle it with a try catch block.ExampleCode Implementation.import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; import java.util.List; public class ...

Read MoreMinimize (max(A[i], B[j], C[k]) – min(A[i], B[j], C[k])) of three different sorted arrays in C++
ConceptWith respect of given three sorted arrays A, B, and C of not necessarily same sizes, compute the lowest i.e. minimum absolute difference between the maximum and minimum number of any triplet A[i], B[j], C[k] such that they are under arrays A, B and C respectively, i.e., minimize (max(A[i], B[j], C[k]) – min(A[i], B[j], C[k])).Input−A : [ 2, 5, 6, 9, 11 ] B : [ 7, 10, 16 ] C : [ 3, 4, 7, 7 ]Output−1ExplanationWhen we select A[i] = 6 , B[j] = 7, C[k] = 7, we get the minimum difference as max(A[i], B[j], C[k]) - ...
