Fib Gen In Python

Recommended Posts

OK this is one of my first programs..

from Tkinter import *

def NextNumber():	count = 0	x = 0	y = 1	while count <= int(Range.get()):		for item in [x]:			listbox.insert(0, item)		z = x		x = z + y		y = z		count = count + 1root = Tk()Title = Label(root, text = "Calculate fib number:")Title.pack()Range = Entry(root)Range.pack()PrintNextNumber = Button(root, text = "   Display   ", command = NextNumber)PrintNextNumber.pack()listbox = Listbox(root)listbox.config(selectborderwidth=1, height=1, width=50)listbox.pack()root.mainloop()

what do you think of it???
comment?... do i have any bad technecs or something?.. i know i havent put any comment in the code

That's pretty cool. It would be easier if you didn't use a GUI, but it's still pretty simple. Personally I'd have done something more like:

def fib_nums_1() #defining the function	count = 0 #We set the count variable to 0 as we have not yet done any production of the numbers	a = 0 #Sets the first variable we require	b = 1 #Sets the second necessary variable	print b #We print the first of our numbers	count = count + 1 #We add one to the count variable as we have processed and printed one fibonacci number	c = a + b #We set the second number to be printed as the sum of the first two	print c #Now we print it	count = count + 1 #We add another one to the count variabledef fib_nums_2() #Now we are defining the second function of our program	a = c + b	print a	count = count + 1	b = a + c	print b	count = count + 1	c =  b + a	count = count + 1fib_nums_1()while count != 100: #This obviously means that we will keep running the following code until the count variable is at 100, at which point we will have calculated and printed 100 fibonacci numbers	fib_nums_2()
