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 python
from selenium import webdriver
from selenium.webdriver.common.by import By
import time
# set webdriver path here it may vary
browser = webdriver.Chrome(
executable_path="C:\Program Files (x86)\Google\Chrome\chromedriver.exe")
website_URL = "https://www.google.co.in/"
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
from 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 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()
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 webdriver
from selenium.webdriver.common.by import By
# time.sleep() function is required because
# selenium needs a page to be fully loaded first
# otherwise errors may occur
import 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 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")
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 Code
instagramBot('Sample Username', 'Sample Password')
