FW: [Tutor] deleting CR within files

[David Talaga]

Here is the whole thing.  See what you can do?  I am stuck and sitting here
looking at it doesn't help my situation...
#This is the dialog.py module:

from Tkinter import *
import tkFileDialog
import sys
def dialog(fileName):
    top = Tk()
    top.withdraw()
    initDir = 'C:/windows/desktop'
    filetype = [('All files', '.*')]
    fileName = tkFileDialog.askopenfilename(initialdir=initDir,
filetypes=filetype)
    return fileName
And here is the crgui.py module:

import os
import Tkinter
import sys
import dialog


root=Tkinter.Tk()
f=Tkinter.Button(root, text="Find Files", command=dialog.dialog).pack()
x=Tkinter.Button(root, text="Close", command=sys.exit).pack()

if f:
    in_file = open(fileName,'r').readlines()
    out_file = open(fileName + '_cleaned', 'w')
    for i in dialog().readline:
        out_file.write(i[:-1] + '\n')
    print 'File cleaned'
    out_file.close()
    print filename

root.mainloop()

The dialog function is not returning the information I believe.  I think
this is where my problem lies.  I am not able to access the text i am trying
to access because I believe that for some reason I am not getting the actual
file, just a printed version of it.

Hi David,

what's the "dialog.dialog", a dialog box widget you wrote yourself, I guess?
Maybe
it works similar to a tkSimpleDialog.askstring() ? Maybe you just should
call

 fileName= dialog.dialog()  ??

Just a shot in the dark, but I think you might have a closer look at the
dialog module.

Michael
