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. 
 

Python




#!/usr / bin / env python
from selenium import webdriver
import time
 
# set webdriver path here it may vary
browser = 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 out
refreshrate = 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 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
browser.get('https://www.zomato.com / ncr')
 
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. 
 

Python3




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
        self.driver.get("https://instagram.com")
        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')
