Hi,

This is my first attempt to write a script with any kind of gui. All I
need the script to do is ask the user for a directory and then do stuff
with the files in that directory. I used tkFileDialog.askdirectory().
It works great but it pops up an empty tk window. Is there any way to
prevent the empty tk window from popping up? Here's the code:


import tkFileDialog

answer = tkFileDialog.askdirectory()

if answer is not '':
#do stuff

Thanks!
Matt

Opps, i see you answered your own question

To save you more hours of Googling take a look at these two sites!

#great reference
http://infohost.nmt.edu/tcc/help/pubs/tkinter/

#more in-depth
http://effbot.org/tkinterbook/

you'll want to keep them both under your pillow.

Opps: And here i go making a clown of myself again...

import Tkinter as tk
from tkFileDialog import askdirectory
import os

root = tk.Tk()
root.withdraw()

folder = askdirectory()
#make sure to do this somewhere that will always execute!
root.destroy()
if folder:
print os.listdir(folder)

root.mainloop()

r... just another would be language designer

Matt,

There is also a nice thing you need to know about Python if you
already do not know. That is the fact that all empty collections bool
to False. This makes Truth testing easier.

>>> bool([])
False
>>> bool('')
False
>>> bool({})
False
>>> bool([1])
True
>>> bool([[]])
True
>>> bool(' ')
True

any empty collection, string, or 0 always bools to False.

Thank you both for all the help. Your suggestions have helped clean up
a bunch of my code.

Thanks!
