You can use Google's SMTP server to send email messages using the Simple Mail Transfer Protocol (SMTP). Here is an example of how to use the smtplib library in Python to send an email using Google's SMTP server:
import smtplib
# create an SMTP object
server = smtplib.SMTP('smtp.gmail.com', 587)
# start the server connection
server.starttls()
# login to the server using your email and password
server.login("your_email@gmail.com", "your_password")
# create the message
from_address = "your_email@gmail.com"
to_address = "recipient_email@example.com"
subject = "Test email from Python"
body = "This is a test email sent from Python using Google's SMTP server."
message = f"Subject: {subject}\n\n{body}"
# send the message
server.sendmail(from_address, to_address, message)
# close the server connection
server.quit()
In this example, "your_email@gmail.com" and "your_password" should be replaced with your actual Google email address and password. Also "recipient_email@example.com" should be replaced with the email address of the recipient.
Please note that if you are using 2-factor authentication then you need to use application-specific password.
