So, how would we go about using a variable to update this label? Tkinter comes with four built-in variable objects for us to handle different data types:
- StringVar: This holds characters like a Python string.
- IntVar: This holds an integer value.
- DoubleVar: This holds a double value (a number with a decimal place).
- BooleanVar: This holds a Boolean to act like a flag.
To create a variable, just instantiate it like any other class. These do not require any arguments. For example:
label_text = tk.StringVar()
