Changing Colours

Well, in this opportunity I got some simple animation that involves a straight line that change its colour between 4 options in a fixed order, it's a relatively simple task, although I've seen codes that involve the use of objects and classes, so I hope to get a better understanding on them before posting about it.

Mach Number Calculator

Code for the simple Mach Number calculator:

from Tkinter import *

def mc():
    # 1st Function
    try:
        ns00, ns01 = a00.get(), a01.get()
        ns02, ns03 = a02.get(), a03.get()
        V = ns00
        k = ns01
        R = ns02
        T = ns03
