[Tutor] Any Suggestions?

[Mark Brown]

Hello,
I'm just learning Python and would appreciate any suggestions regarding
the programs listed below.  The programs do function.

runit2.py
#!/usr/bin/env python

import runit2tk
from os import system
from sys import exit

gui1 = runit2tk.Gui1()
gui1.mainloop()

if gui1.text != "":
    command = "%s &" % gui1.text
    system(command)

exit(0)


runit2tk.py
#!/usr/bin/env python

import Tkinter

class Gui1:
	def __init__(self, text=""):
	    self.text = text
            self.root = Tkinter.Tk()
            self.root.title('PyRun')
            self.label = Tkinter.Label(self.root, text="Run")
            self.label.pack(side="left")
            self.entry = Tkinter.Entry(self.root, takefocus="true")
            self.entry.pack(side="left", fill="x", expand="true")
            self.entry.bind('<Key-Return>', self.getinput)
            self.entry.focus()

        def mainloop(self):
	    self.root.mainloop()

        def getinput(self, event):
            self.text = self.entry.get()
            self.root.destroy()
            return self.text


Thanks
