def send_email(message):
    host = "smtp.gmail.com"
    port = 465

    username = "[email protected]"
    password = os.environ.get("pswrd")

    receiver = "[email protected]"
    context = ssl.create_default_context()

    with smtplib.SMTP_SSL(host, port, context=context) as server:
        server.login(username, password)
        server.sendmail(username, receiver, message)

I used this code to send mail in my program and created a environment variable to secure my password in it from control panel > System and Security > System > Advanced system Settings>Environment Variables but it is showing that the password as not accepted when i used os.environ.get("pswrd") in python console it is also showing none
