質問:
GmailAPIを使わずにPythonでGmailを自動送信するスクリプトを教えてください

ChatGPT回答:
Gmail APIを使わずにGmailを自動送信するには、SMTP（Simple Mail Transfer Protocol）を使うことができます。
次のようなコードを記述することでGmailを自動送信することができます：
import smtplib
from email.mime.text import MIMEText

def send_email(to, subject, body):
    gmail_user = 'your_gmail_address@gmail.com'
    gmail_password = 'your_gmail_password'

    msg = MIMEText(body)
    msg['Subject'] = subject
    msg['From'] = gmail_user
    msg['To'] = to

    try:
        server = smtplib.SMTP_SSL('smtp.gmail.com', 465)
        server.ehlo()
        server.login(gmail_user, gmail_password)
        server.send_message(msg)
        server.quit()
        print(F'Email was sent to "{to}"')
    except Exception as e:
        print(F'Something went wrong... {e}')
このスクリプトを実行すると、指定された宛先にメールが送信されます。
Gmailアカウントを使用する場合は、Gmailアカウントにアクセスするためのユーザー名とパスワードを設定する必要があります。

import smtplib
from email.mime.text import MIMEText

def send_gmail(mailto, title, text_msg):
    from_email ='送信元Gmailアドレス' 
    cc_mail = ''
    
    msg = MIMEText(text_msg, 'plain')
    msg['Subject'] = title
    msg['To'] = mailto
    msg['From'] = from_email
    msg['cc'] = cc_mail
    
    smtp_host = 'smtp.gmail.com'
    smtp_port = 587
    smtp_password = '2段階認証非対応デバイス用パスワード'
    
    server = smtplib.SMTP(smtp_host, smtp_port)
    server.starttls()
    server.login(from_email, smtp_password)
    server.send_message(msg)
    server.quit()

from my_library import gmail

mailto = "送信先メールアドレス"
title = "テスト"
msg = "テスト\nメール"

gmail.send_gmail(mailto, title, msg)
