Tkinter SimpleDialog

This article covers Tkinter SimpleDialog, which is a sub class of Tkinter.

The SimpleDialog module is used to create dialog boxes to take input from the user in a variety of ways. SimpleDialog allows us to take input of varying datatypes from the user, such as float, string and integer.

The below Tkinter SimpleDialog functions work together with tkinter. A tkinter window is required for these functions to work. If a tkinter window is not present, these functions will create one by default.

SimpleDialog – askinteger

The askinteger() function is used to get an integer from the user. It accepts only int values.

from tkinter.simpledialog import askinteger

root = tk.Tk()
prompt = askinteger("Input", "Input an Integer")

SimpleDialog – askfloat

The askfloat() function is used to get float values from the user. It accepts integer values, but returns them in float format.

from tkinter.simpledialog import askfloat

root = tk.Tk()
prompt = askfloat("Input", "Input an Float")

SimpleDialog – askstring

The askstring() function is used to get a string from the user. You can pass values of any type to it, but it will return them in string format.

from tkinter.simpledialog import askstring

root = tk.Tk()
prompt = askstring("Input", "Input an String")

An interesting side note. If you pass an string value into the float function for instance, it will not throw an exception and terminate the program. A simple error prompt will be shown, and the program will continue as normal.

If you only want to show a simple dialog with only text (no inputs), then take a look at the Tkinter messagebox widget.
