Hello, checkiomates🐱‍👤!

Try a video course about creating some basic application with Tkinter and find out in what order a gator eats ducks. Sounds funny, yeah?

Gator And Ducks by freeman_lex -

Suppose there are ducks floating on the pond in a circle. The pond is also home for alligator with a fondness for ducks. Beginning at a particular position (duck number 1) the alligator counts clockwise around the circle and eats every step-th duck (the circle closing as ducks are eaten). Write a script which returns the orders of consumption of the ducks given ducks, step.

gator(8, 4) == [5, 4, 6, 1, 3, 8, 7, 2]
gator(7, 11) == [7, 2, 3, 1, 5, 6, 4]
gator(3, 1) == [1, 2, 3]

Building a Python GUI Application With Tkinter -

Python has a lot of GUI frameworks, but Tkinter is the only framework that’s built into the Python standard library. It’s cross-platform, visual elements are rendered using native operating system elements, lightweight and relatively painless to use compared to other frameworks. This makes it a compelling choice for building GUI applications in Python, especially for applications where a modern sheen is unnecessary. In this video course you will start with some simple applications.

👩‍💻CODE SHOT

This one is longer, but simple. How do you think, what the following code does?

from math import pi, sqrt

def ????????(*args):
    match len(args):
        case 1:
            res = pi * args[0] **2 /4
        case 2:
            res = args[0] * args[1]
        case 3:
            a, b, c = args
            res = sqrt((a + b + c)*(a + b - c)*(a + c - b)*(b + c - a))/4
    return round(res, 2)
