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 from selenium.webdriver.common.by import By 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.
Trick 1: 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.
Python
#!/usr / bin / env pythonfrom selenium import webdriverfrom selenium.webdriver.common.by import Byimport time# set webdriver path here it may varybrowser = webdriver.Chrome( executable_path="C:\Program Files (x86)\Google\Chrome\chromedriver.exe")browser.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 outrefreshrate = int(15)# This would keep running until you stop the compiler.while True: time.sleep(refreshrate) browser.refresh() |
Trick2: How to login on a website, here we take example of Zomato
Python
from selenium import webdriverfrom selenium.webdriver.common.by import By# For using sleep function because selenium# works only when all the elements of the# page is loaded.import time# webdriver path setbrowser = webdriver.Chrome( "C:\Program Files (x86)\Google\Chrome\chromedriver.exe")# To maximize the browser windowbrowser.maximize_window()# zomato link settime.sleep(3)# Enter your user name and password here.username = "test"password = "test"# signin element clickedbrowser.find_element(By.XPATH, "//a[@id ='signin-link']").click()time.sleep(2)# Login clickedbrowser.find_element(By.XPATH, "//a[@id ='login-email']").click()# username senda = browser.find_element(By.XPATH, "//input[@id ='ld-email']")a.send_keys(username)# password sendb = browser.find_element(By.XPATH, "//input[@id ='ld-password']")b.send_keys(password)# submit button clickedbrowser.find_element(By.XPATH, "//input[@id ='ld-submit-global']").click()print('Login Successful')browser.close() |
Trick 3: 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.
Python3
from selenium import webdriverfrom selenium.webdriver.common.by import By# time.sleep() function is required because# selenium needs a page to be fully loaded first# otherwise errors may occurimport time# Usage time.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 requiredclass 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 time.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() time.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 CodeinstagramBot('Sample Username', 'Sample Password') |
