I want to know, how to pop-up messages when executing / executing the program / function I mean, 

  def (): path = tkFileDialog.askopenfilename (filetypes = [("image file", '.jpg')]) im = skimage.io.imread (path, As_grey = true) im = skimage.img_as_ubyte (im) im / = 32g = skimage.feature.greycomatrix (im, [1], [0], level = 8, symmetically = wrong, criterion = true) cont = skimage Feature.greycoprops (g, 'contrast') [0] [0] cont_list1.append (cont) ene = skimage.feature.greycoprops (g, 'energy') [0] [0] ene_list1.append (ene) homo = Skimage.feature.greycoprops (g, 'homogeneity') [0] [0] home_list 1.append (homo) cor = skimage.feature.greycoprops (g, 'correlation') [0] [0] cor_list1.append (cor ) Dis = skimage.feature.greycoprops (g, 'difimilarity') [0] [0] dis_list1.append (dis)   
 I want to display a message stating that the features Calculating, and once computing, the message should disappear.  
   
 but I  fine  Button is not required. I do not know how to get it. The results of these calculations will be welcome any suggestions displayed in the separate entry box are welcome.   
 
 
 Take a look at this. It opens a window with the text and when the calculation is done, the text is converted into result.  
  & gt; & Gt; & Gt; Import time & gt; & Gt; & Gt; Convert DQF Processing: Import, Typographer, Time, Threading Window = Tanker. Local () # or Tankinor The label starts before coding (TK). Tkinter.Label (window, text = text) label.pack () done = [] def call (): result = function () done.append (result) thread = threading Thread thread (target = call) thread.start () # parallel computing # thread.is_alive (): #include window.update (code) time.sleep (0.001) during code # code when calculation is labeled ['text' ] = Str (done)> gt; & Gt; & Gt; ProcessingPleaseWait ('Wait 2 seconds ...', lambda: time.sleep (2))

I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job.

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
