What is IntVar () in tkinter?

Moreover, what is IntVar () in Python?

For DoubleVar variables, the returned value is a Python float. For IntVar, it's an integer. For StringVar, it's either an ASCII string or a Unicode string, depending on the contents. The set method updates the variable, and notifies all variable observers. You can either pass in a value of the right type, or a string.

Beside above, what is string var? String variables are variables that hold zero or more characters such as letters, numbers, spaces, commas and many more. You can't use numeric functions such as addition or subtraction on string variables.

Secondly, what is StringVar in tkinter?

Tkinter is a wrapper around an embedded tcl interpreter. StringVar is a class that provides helper functions for directly creating and accessing such variables in that interpreter. Once tkinter has been properly initialized and a StringVar instance has been created, it can be treated like any other python object.
