Selenium Python Tricks
  • Difficulty Level : Medium
  • Last Updated : 18 May, 2020

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


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")
# 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:

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
# zomato link set
browser.get(' / ncr')
# Enter your user name and password here.
username = "test"
password = "test"
# signin element clicked
browser.find_element_by_xpath("//a[@id ='signin-link']").click()
# Login clicked
browser.find_element_by_xpath("//a[@id ='login-email']").click()
# username send
a = browser.find_element_by_xpath("//input[@id ='ld-email']")
# password send
b = browser.find_element_by_xpath("//input[@id ='ld-password']")
# submit button clicked
browser.find_element_by_xpath("//input[@id ='ld-submit-global']").click()
print('Login Successful')

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()
        # 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')
