How do you put the OUTPUT into a GUI in Tkinter?

[Gloryness]

• I'm asking a question
• I've looked through the README and FAQ for similar questions
• I've searched the bugtracker for similar questions including closed ones

This is for Python, not the terminal.

I'm building a GUI for downloading videos. It's coming along really well, but I need to somehow get the downloading output that you see in the terminal/console, into a Text-GUI in tkinter.

• I have changed the stdout to the text box, but whenever I download something, it crashes - as if all of a sudden it forces the output to not be in the GUI causing it to crash and then says:
  "Process finished with exit code 120"

I'd appreciate any help!
