Although there are Python modules [1,2,3] specially suited for displaying text to the console in color, if you want a quick no-dependency method then you can use ANSI color codes directly.
Here is an example of printing a line in green, then red.
print("\033[0;32mOK this is green\033[00m")
print("\033[0;31mERROR this is red\033[00m")
Additional color codes can be found here and here. I’ve uploaded a full example to github.
