How do I catch the output of command dcfldd that goes to the terminal in Linux and show output in real time in python ?

This video shows the numbers in the same line, how do I get this in real time before end process?

  • *"not work"* is not very informative: [create a minimal but complete code example](http://stackoverflow.com/help/mcve) that shows the issue and add it to the answer (click [edit] under the question). – jfs Oct 15 '15 at 08:12
