Selenium: Selenium Python bindings provide a convenient API to access Selenium Web Driver like Firefox, Chrome, etc.
What is webdriver?
Selenium WebDriver is an automation testing tool. When I say automation, it means it automates test scripts written in Selenium.
Webdriver Install
Chrome: https://sites.google.com/a/chromium.org/chromedriver/downloads
Library Imported
from selenium import webdriver import time
(i) Selenium library:
– Used for Automation
– Control Webdriver
– Perform actions like – element clicks, refresh page, goto website link, etc
(ii) Time library:
-For using sleep function because selenium works only when all the elements of the page is loaded.
Trick1: How to increase view count on a website?
#Note: This will not work on all websites, like youtube.
What we would be learning is to refresh the webpage again and again after a particular interval of time.
#!/usr / bin / env python from selenium import webdriver import time # set webdriver path here it may vary brower = webdriver.Chrome(executable_path ="C:\Program Files (x86)\Google\Chrome\chromedriver.exe") brower.get(website_URL) # After how many seconds you want to refresh the webpage # Few website count view if you stay there # for a particular time # you have to figure that out refreshrate = int(15) # This would keep running until you stop the compiler. while True: time.sleep(refreshrate) brower.refresh() |
Trick2: How to login on a website, here we take example of Zomato
from selenium import webdriver # For using sleep function because selenium # works only when all the elements of the # page is loaded. import time # webdriver path set browser = webdriver.Chrome("C:\Program Files (x86)\Google\Chrome\chromedriver.exe") # To maximize the browser window browser.maximize_window() # zomato link set time.sleep(3) # Enter your user name and password here. username = "test"password = "test" # signin element clicked browser.find_element_by_xpath("//a[@id ='signin-link']").click() time.sleep(2) # Login clicked browser.find_element_by_xpath("//a[@id ='login-email']").click() # username send a = browser.find_element_by_xpath("//input[@id ='ld-email']") a.send_keys(username) # password send b = browser.find_element_by_xpath("//input[@id ='ld-password']") b.send_keys(password) # submit button clicked browser.find_element_by_xpath("//input[@id ='ld-submit-global']").click() print('Login Successful') browser.close() |
Trick3: Instagram Login automation script.
We know that Instagram is discontinuing its Legacy API from 29 June, 2020.
So it’s probably a better idea to learn automation scripting.
from selenium import webdriver # sleep() function is required because # selenium needs a page to be fully loaded first # otherwise errors may occur from time import sleep # Usage sleep(x) Where x is time in seconds and # may vary according to your connection # I have made class so that extra methods can be added later on # if required class instagramBot: def __init__(self, username, password): # these lines will help if someone faces issues like # chrome closes after execution self.opts = webdriver.ChromeOptions() self.opts.add_experimental_option("detach", True) self.driver = webdriver.Chrome(options=self.opts) # Username and password self.username = username self.password = password # Opens Instagram login page sleep(2) # 1 Second Wait # Automatically enters your username and # password to instagram's username field self.driver.find_element_by_xpath("//input[@name = 'username']").send_keys(self.username) self.driver.find_element_by_xpath("//input[@name = 'password']").send_keys(self.password) # Clicks on Log In Button self.driver.find_element_by_xpath("//div[contains(text(), 'Log In')]").click() sleep(2) # Bonus: Automatically clicks on 'Not Now' # when Instagram asks to show notifications self.driver.find_element_by_xpath("//button[contains(text(), 'Not Now')]").click() # Testing Your Code instagramBot('Sample Username','Sample Password') |
