This CTkinter GUI app allows you to send a appointment confirmation email with the date of the appointment selected.

pip install Tkinter

pip install customTkinter

pip install TkCalendar

Must Enable 2 Factor Authentication With Google Account and Generate an App Password

You must change this for the email to send:

email_sender= '[email protected]'  #Enter your email here
email_pass = 'yourapppassword'       #Enter your app password here

When trying to package a CTkinter GUI Program as an executable I recommend using auto-py-to-exe (a bit more user friendly than pyinstaller)

To Install auto-py-to-exe:

pip install auto-py-to-exe

Open auto-py-to-exe:

python -m auto_py_to_exe

This should open auto-py-to-exe. Once inside you must use One Directory (--onedir¹) and Add Folders customtkinter, babel, TkCalendar in Additional Files (--add-data¹)
