Python3 Tkinter Messagebox
In this article, you will learn different Tkinter messagebox in Python3.
Tkinter is a standard cross-platform package for creating graphical user interfaces (GUIs). It is also called Tk interface. It is an original GUI library for Tcl (Tool Command Language). Tkinter comes pre-installed with Python. Tkinter provides MessageBox Widget to display message box widgets in Python applications.
In some applications, we need to show a message box to receive the user's input, like - True, False, Yes, No, OK, None. The messagebox widget has various methods to show different message box graphical user interfaces.
messagebox.functionName(title, message , options)Here, functionname is an appropriate message box function name, title is the message box title, message is a text display on message boxes.
The options are an optional choice to create a standard message box. There are two most commonly used options - default and parent. The default option specifies the default button, like ABORT, RETRY, or IGNORE, in the message box. The parent option is used to specify on top of which parent window the message box is to be displayed.
