This project is based on the serialization of files based on the Tkinter framework which, based on a preliminary file, publishes a following file, increasing its complexity and usefulness. Each file is listed in the same file name (template1, template2, template3 ...) so that individually they can be useful as templates for different projects.
I must say that my interest in this wonderful miniframework called Tkinter (better known as the surprise Kinder Eggs), started with a project that had in common with the teachings of the Cisco Networking Academy. Said GitHub project to which I have marked the star is dedicated to Cisco Systems APIC-EM drivers, I have the same drivers but this one unlike mine incorporates Tkinter. I think it's from a German engineer if I'm not mistaken: click right here to see it. I really liked the idea of incorporating an interface to a networking program, which as we know usually works normally with the command line. So I started creating a small collection of templates Tk or Tkk or Tkkk or Tkkkk or ... 🤢 only to obtain guidelines and to be able to flexibilize and share knowledge with you if you decide to cooperate in my templates project, where you are welcome.
Here is an example of template number 10, which is a small data entry interface of an IBAN validator, based on my first GitHub project, which had no interface: click right here if you are curious to see it.
