This is a Python script for tracking attendance, sending email notifications to absentees, and checking if the attendance is above or below a specified threshold. It uses the openpyxl library for Excel file handling and the smtplib library for sending emails.

• Load attendance data from an Excel file.
• Save attendance data to the same Excel file.
• Send email notifications to absentees.
• Check if the attendance is above or below a specified threshold.

• Python 3.x installed.
• Required Python libraries can be installed using pip:

pip install openpyxl

Before using the script, make sure to configure the following variables in the code:

• attendance_file: The path to the Excel file containing attendance data.
• threshold: The attendance percentage threshold for sending notifications.
• email_config: Email configuration, including the SMTP server, sender's email address, and email message.

1. Run the track_attendance function in the script to track attendance and send email notifications to absentees:

   python attendance_tracker.py
   

2. The script will load attendance data, calculate attendance percentage, send email notifications to absentees, and print whether the attendance is above or below the threshold.

• openpyxl for Excel file handling.
• smtplib for sending email notifications.
