Sending gmail with Python. This version uses the ssl module and SMTP_SSL() from the smtplib module.

send_gmail.py

import smtplib
import ssl
from email.mime.text import MIMEText

sender = "[email protected]"
receiver = "[email protected]"
password = input("Enter password: ")

text = """\
Hi!

This is a test email send with Python.

Have a great day!"""

message = MIMEText(text)
message["Subject"] = "Sending email with Python!"
message["From"] = sender
message["To"] = receiver

# create a secure SSL context
context = ssl.create_default_context()

# using a 'with' context manager will make sure the connection
# is automatically closed at the end of the indented code block
with smtplib.SMTP_SSL("smtp.gmail.com", 465, context=context) as s:
    s.login(sender, password)
    s.sendmail(sender, receiver, message.as_string())
