Instructions to Run:

To send a mail

• For safety, preferably generate an app password for the sender gmail account in case it has 2-step verification enabled.
• Otherwise, you need to change a setting in the Gmail account to ensure you can send a mail.
• Head to this website: https://myaccount.google.com/lesssecureapps
• Make sure the setting is turned ON. If not, Python cannot log into your Gmail account.

To send a WhatsApp message

• While running the send_msg() function, a Chrome browser while pop up and you should see a screen that asks you to scan a QR code to log into WhatsApp. It means you need to manually use your phone to scan it before the program can access your WhatsApp profile.
• To fix this, create a folder called “whatsapp_profile” in the current working directory. You can choose any location and any folder name.
• In the pricecheck.py file, you'll notice I have already created this file and mentioned the path as

'user-data-dir=/Users/anweashasaha/Desktop/whatsapp_profile'

• Replace

'/Users/anweashasaha/Desktop/whatsapp_profile'

with the path of your "whatsapp_profile" folder.

• After making these changes and running the code, you’ll get a bunch of files populated in the “whatsapp_profile” folder.
• A Chrome browser should open up with the WhatsApp page. Go ahead and use your phone to scan the QR code to log in.
• After logging in, you can close the browser and Selenium.
• Try re-running the code, this time you should land on a WhatsApp page that’s already logged in. But this time use the following code

option=Options()
driver = webdriver.Chrome('/opt/homebrew/bin/chromedriver',options=option)
driver.get(url1)

instead of

option=Options()
option.add_argument(r'user-data-dir=/Users/anweashasaha/Desktop/whatsapp_profile')
driver = webdriver.Chrome('/opt/homebrew/bin/chromedriver',options=option)
driver.get(url1)

otherwise you'll get an error.
