Documentation

• The tkinter Python module is among the standard library modules described at docs.python.org. This documentation provides an overview, not a detailed API specification, to Tk.
• The ttk extension to Tk introduced more widgets and styling options. It's also described at docs.python.org. The docs.python.org page for ttk is a more thorough, but not complete, API specification.
• For more information about Tk in general and how it can be accessed from various programming languages, see https://tkdocs.com/.
• The first language to use Tk was Tcl, a command-line language like the shell. You can learn more about Tcl commands and Tk and ttk specific commands at the www.tkl.tk website
