This is how you can send an email through python using smtp and ssl(Secure Sockets Layer, an encryption protocol)

Following will be the code to send an email through python and I will be explaining every critical step in the comments indicated with #

import smtplib, ssl

port = 465  # For SSL
smtp_server = "smtp.gmail.com"
sender_email = "youremail@gmail.com"  # Enter your address
receiver_email = "reciever@gmail.com"  # Enter receiver address
password = "YourPassword"  #this password will be the one you generate after
#you login with your account and then after enabling 2fa, you will go to app passwords
#and there you can generate an app password
message = """\             
Subject: Hi there

This message is sent from Python.
"""

context = ssl.create_default_context()
with smtplib.SMTP_SSL(smtp_server, port, context=context) as server:
    server.login(sender_email, password)
    server.sendmail(sender_email, receiver_email, message
#here the code is pretty self explanatory, we will, through the help of 
#server.sendmail(), send a mail to the receiver
