Maybe a button is also necessary? > Hi Dick, assuming the functions you want to use are in a separate module "fact.py", a simple (and dirty) solution might look like from Tkinter import * import fact root = Tk() entry = Entry(root) entry.pack(side='top') text = Text(root) text.pack(side='top') # now you need a callback that calls fact() and inserts the result into the text widget def compute_fact(): value = int(entry_get()) result = fact.fact(value) newtext = 'Result: %d\n' % result# change this to the output format you wish text.insert('end', result) button = Button(root, text="Compute fact", command=compute_fact) button.pack(side='top') root.mainloop() In case you do not want an extra button, you can bind the compute_fact() callback to Key-Return events for the entry: entry.bind('<Return>', compute_fact) however you will have to change the callback's constructor to accept an event object as argument: def compute_fact(event): (...) or : def compute_fact(event=None): (...) which allows both. In case you want the output formatting done in the fact module, change the printFact() function, so that it *returns* a string instead of printing it to stdout, so you can use a callback like: def compute_fact(event=None): text.insert('end', fact.printFact(int(entry.get()))) I hope this helps Michael _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
