Tkinter

My adventure with Tcl/Tk led me to compare it to my go-to scripting language, Python. Here is the simplest version of Euler1 in Python's port of Tk, Tkinter, a platform-independent GUI toolkit introduced in the mid '90s. I have to say, there really is no comparison - as much as I love me some Python, Tkinter requires 13 lines to display the simplest HelloWorld, whereas Tcl/Tk requires only two. However, Tcl's version of the Euler1 algorithm took 7 lines while Python's took 2. And it took me probably five minutes to write this. So overall, it's a tie:

#!/usr/bin/python
# Euler1 in Tkinter
from Tkinter import *

def euler1(x):
    return sum(i for i in range(x) if i%3==0 or i%5==0)

class Application(Frame):
    def __init__(self, master=None):
        Frame.__init__(self, master)

        self.QUIT = Button(self)
        self.QUIT["text"] = euler1(1000)
        self.QUIT["command"] =  self.quit
        self.QUIT.pack({"side": "left"})
        self.pack()

root = Tk()
app = Application(master=root)
app.mainloop()
root.destroy()

To run, simply call your script:

$ euler1.tk.py

And here is the result:
