def Fibonacci(n): 
    if n < 0: 
        print("Incorrect input") 
    elif n == 1: 
        return 0
    elif n == 2: 
        return 1
        return Fibonacci(n - 1)+Fibonacci(n - 2)

A simple fibonnaci example. This code example is 100% compatible with Python, while showing the great perfomance of Flyable.

            import Window,Label from flygui

def main(): 
	a = Window("Title of my window",Label("Hello World!"))

A simple code example that shows you how easy it is to create a cross-platform GUI with Flyable.
