title: I would like to pass the value entered into the textbox to a python program
body: <p>I wrote this code</p>
  
  <pre><code>app = Tk()
  app.title('Myapp')
  app.geometry('260x100+50+50')
  
  labelText =StringVar()
  labelText.set('Insert the version you want to check')
  label1 = Label(app, textvar=labelText, height=4)
  label1.pack()
  
  stringadacercare = StringVar(None)
  lastringa = Entry(app, textvar=stringadacercare)
  lastringa.place(x=30, y=40, width=200)
  
  
  progressbar = ttk.Progressbar(orient=HORIZONTAL, length=260, mode='determinate')
  progressbar.pack(side='bottom')
  progressbar.start()
  
  app.mainloop()
  </code></pre>
  
  <p>I would like to pass the input taken by the textbox into this program instead of the raw_input so binding it to testV </p>
  
  <pre><code> import csv
   import re
   import os
   testV = raw_input('Insert the version you want to find: ')
   fileobj = csv.reader(open('c:\\paths1.csv', 'rb'), delimiter=' ', quotechar='|')
   for row in fileobj:
  
  for x in row:
      with open(x) as f:
          for line in f:
  
              if re.match(testV, line):
                  print 'The version match: '+ line
              else:
                  print 'wrong version'     
      filesize= os.path.getsize(x)
  print 'The file size is :'+ str(filesize) +' bytes';
  </code></pre>
  
  <p>Could anyone help me out?
  Thank you in advance!!!!!</p>
