Logfile for my App not "rewriting"

[Adam]

Hello,

I have a small app I am creating to crawl a directory and check that
if it is moved to another a location it's path will not break a
character limit. Usually the Windows path limit.

Now the script is working but every time I want to scan again I have
to restart for the log files to be written. I want to just be able to
change the parameter as I please and click scan without having to
restart the app for the log file to change.
(I am new to programming so the code could be untidy for want of a
better word.)

Here's the code:

#indentation value 4

(width,height, x, y)
self.labAll = tk.Label(self.mainWindow, text="All Files/
Folders:")
self.labVi = tk.Label(self.mainWindow, text="Violating Files/
Folders:")

#Create a sub-frame containing textbox and scrollbar for All
files scanned display
self.allTxtf = tk.Frame(self.mainWindow, width=700,
height=164)

self.txtBoxall = tk.Text(self.allTxtf, wrap=tk.CHAR,
yscrollcommand=self.scrlr1.set, width=700, height=164)
self.scrlr1.config(command = self.txtBoxall.yview)

#Create another sub-frame containing textbox and scrollbar for
the Violating files display
