Question

I have created a program that prints results on command line. (It is server and it prints log on command line.)

Now, I want to see the same result to GUI .

How can I redirect command line results to GUI?

Please, suggest a trick to easily transform console application to simple GUI.

Note that it should work on Linux and Windows.

You could create a script wrapper that runs your command line program as a sub process, then add the output to something like a text widget.

from tkinter import * import subprocess as sub p = sub.Popen('./script',stdout=sub.PIPE,stderr=sub.PIPE) output, errors = p.communicate()  root = Tk() text = Text(root) text.pack() text.insert(END, output) root.mainloop() 

where script is your program. You can obviously print the errors in a different colour, or something like that.
