tkFileDialog question

[Matt Mitchell]

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!
