# assign web page url |
- using By.TAG_NAME find web link in webpage.
Implementation:
Python3
#import module from selenium import webdriver from selenium.webdriver.common.by import By driver = webdriver.Chrome() # url # find web links link = driver.find_elements(By.TAG_NAME, 'a') # using len function count how many links print(len(link)) |
Output:
