How do you create a slider in Python?

How does the scale widget work in Tkinter?
Using the Scale widget creates a graphical object, which allows the user to select a numerical value by moving a knob along a scale of a range of values. The minimum and maximum values can be set as parameters, as well as the resolution. We can also determine if we want the slider vertically or horizontally positioned.
Which is better a scale widget or a slider?
A Scale widget is a good alternative to an Entry widget, if the user is supposed to put in a number from a finite range, i.e. a bounded numerical value. We have demonstrated in the previous example how to create sliders. But it’s not enough to have a slider, we also need a method to query it’s value. We can accomplish this with the get method.
Is it possible to generate random data in Python?
First, a prominent disclaimer is necessary. Most random data generated with Python is not fully random in the scientific sense of the word. Rather, it is pseudorandom: generated with a pseudorandom number generator (PRNG), which is essentially any algorithm for generating seemingly random but still reproducible data. “True”…
Is there a way to make scale widgets unresponsive?
You can change that length by setting the sliderlength option to your desired length. Normally, scale widgets respond to mouse events, and when they have the focus, also keyboard events. Set state=DISABLED to make the widget unresponsive. Normally, the focus will cycle through scale widgets.
Which is the control variable for a scale widget?
The way your program reads the current value shown in a scale widget is through a control variable. The control variable for a scale can be an IntVar, a DoubleVar (float), or a StringVar. If it is a string variable, the digits option controls how many digits to use when the numeric scale value is converted to a string.
What are the parameters of Tkinter scale in Python?

When does mouse cursor change in Tkinter scale?
If the slider is moved rapidly, you may not get a callback for every possible position, but you’ll certainly get a callback when it settles. If you set this option to a cursor name ( arrow, dot etc. ), the mouse cursor will change to that pattern when it is over the scale.
