To automate sending daily email reports in Python, you can use the smtplib library for sending emails and schedule library for scheduling the task to run daily. 
Script to automate sending daily email reports in Python


Here's a simple example script:

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
import schedule
import time

def send_email(subject, body, to_email, smtp_server, smtp_port, smtp_username, smtp_password):
    # Create a MIME object
    msg = MIMEMultipart()
    msg['From'] = smtp_username
    msg['To'] = to_email
    msg['Subject'] = subject

    # Attach the body of the email
    msg.attach(MIMEText(body, 'plain'))

    # Establish a connection to the SMTP server
    with smtplib.SMTP(smtp_server, smtp_port) as server:
        # Log in to the SMTP server if authentication is required
        server.login(smtp_username, smtp_password)

        # Send the email
        server.sendmail(smtp_username, to_email, msg.as_string())

def daily_report():
    # Customize these variables with your own values
    subject = "Daily Report"
    body = "This is your daily report email."
    to_email = "recipient@example.com"
    smtp_server = "smtp.example.com"
    smtp_port = 587  # Adjust the port according to your SMTP server configuration
    smtp_username = "your_username"
    smtp_password = "your_password"

    # Send the email
    send_email(subject, body, to_email, smtp_server, smtp_port, smtp_username, smtp_password)

# Schedule the job to run daily at a specific time (adjust as needed)
schedule.every().day.at("08:00").do(daily_report)

while True:
    # Run pending scheduled jobs
    schedule.run_pending()
    time.sleep(1)
Here's how you can set it up:

Install Required Libraries:

Make sure you have the smtplib, schedule, and email libraries installed. You can install them using:
pip install secure-smtplib
pip install schedule

Configure Email and Schedule:

Replace the placeholder values in the daily_report function with your actual email content and SMTP server details.
Adjust the schedule in the schedule.every().day.at("08:00").do(daily_report) line to your desired daily sending time.

Run the Script:

Save the script with a .py extension (e.g., email_report_script.py) and run it using:
python email_report_script.py
The script will keep running and send the daily email at the specified time.

Note: Make sure to use an application-specific password or enable "less secure apps" in your Google account settings if you are using Gmail. Always be cautious about storing sensitive information like passwords in your code, and consider using environment variables or a configuration file for better security.
