Ok. I think I got it. I have to do it in this way:
###########################
import Tkinter
import tkFileDialog
filename=''
root = Tkinter.Tk()
Tkinter.Button(root, text='Notch genes...', command=lambda:
open_file_dialog()).pack()
def open_file_dialog():
global filename
filename = tkFileDialog.askopenfilename(filetypes=
[("allfiles","*")])
print_filename()
def print_filename():
print filename
root.mainloop()
###########################
Thanks again
