You can try this with python 3   from termcolor import colored print colored  Hello  World     green    on red      If you are using windows operating system  the above code may not work for you  Then you can try this code   from colorama import init from termcolor import colored    use Colorama to make Termcolor work on Windows too init      then use Termcolor for all colored text output print colored  Hello  World     green    on red      Hope that helps

Compared to the methods listed here  I prefer the method that comes with the system  Here  I provide a better method without third-party libraries  class colors    You may need to change color settings     RED     033 31m      ENDC     033 m      GREEN     033 32m      YELLOW     033 33m      BLUE     033 34m   print colors RED    quot something you want to print in red color quot    colors ENDC  print colors GREEN    quot something you want to print in green color quot    colors ENDC  print  quot something you want to print in system default color quot    More color code   ref to   Printing Colored Text in Python Enjoy yourself

What about the ansicolors library  You can simple do   from colors import color  red  blue    common colors print red  This is red    print blue  This is blue       colors by name or code print color  Print colors by name or code    white     8a2be2

I suggest sty  It s similar to colorama  but less verbose and it supports 8bit and 24bit colors  You can also extend the color register with your own colors   Examples   from sty import fg  bg  ef  rs  foo   fg red    This is red text     fg rs bar   bg blue    This has a blue background     bg rs baz   ef italic    This is italic text    rs italic qux   fg 201     This is pink text using 8bit colors    fg rs qui   fg 255  10  10     This is red text using 24bit colors     fg rs    Add custom colors   from sty import Style  RgbFg  fg orange   Style RgbFg 255  150  50    buf   fg orange    Yay  Im orange     fg rs  print foo  bar  baz  qux  qui  buf  sep   n       Demo

There are a few libraries that help out here  For cmdline tools I sometimes use colorama   e g   from colorama import init  Fore  Back  Style init    def cprint msg  foreground    black   background    white        fground   foreground upper       bground   background upper       style   getattr Fore  fground    getattr Back  bground      print style   msg   Style RESET ALL   cprint  colorful output  wohoo    red    black     But instead of using strings  you might want to use an enum and or add a few checks  Not the prettiest solution  but works on osx linux and windows and is easy to use   Other threads about this topic and cross-platform support  e g  here

Would the Python termcolor module do  This would be a rough equivalent for some uses   from termcolor import colored  print colored  hello    red    colored  world    green     The example is right from this post  which has a lot more   Here is a part of the example from docs  import sys from termcolor import colored  cprint  text   colored  Hello  World     red   attrs   reverse    blink    print text  cprint  Hello  World     green    on red     A specific requirement was to set the color  and presumably other terminal attributes  so that all following prints are that way  While I stated in the original post that this is possible with this module I now don t think so  See the last section for a way to do that   However  most of the time we print short segments of text in color  a line or two   So the interface in these examples may be a better fit than to  turn on  a color  print  and then turn it off   Like in the Perl example shown    Perhaphs you can add optional argument s  to your print function for coloring the output as well  and in the function use module s functions to color the text  This also makes it easier to resolve occasional conflicts between formatting and coloring   Just a thought     Here is a basic approach to set the terminal so that all following prints are rendered with a given color  attributes  or mode   Once an appropriate ANSI sequence is sent to the terminal  all following text is rendered that way   Thus if we want all text printed to this terminal in the future to be bright bold red  print ESC  followed by the codes for  bright  attribute  1  and red color  31   followed by m    print   033 1 31m      this would emit a new line as well import sys sys stdout write   033 1 31m   print  All following prints will be red        To turn off any previously set attributes use 0 for attribute   033 0 35m  magenta    To suppress a new line in python 3 use print        end       The rest of the job is about packaging this for modular use  and for easier digestion    File colors py  RED       033 1 31m    BLUE      033 1 34m  CYAN      033 1 36m  GREEN     033 0 32m  RESET     033 0 0m  BOLD        033  1m  REVERSE     033  7m    I recommend a quick read through some references on codes  Colors and attributes can be combined and one can put together a nice list in this package  A script  import sys from colors import    sys stdout write RED  print  All following prints rendered in red  until changed   sys stdout write REVERSE   CYAN  print  From now on change to cyan  in reverse mode  print  NOTE   CYAN   REVERSE  wouldn t work   sys stdout write RESET  print   REVERSE  and similar modes need be reset explicitly  print  For color alone this is not needed  just change to new color  print  All normal prints after  RESET  above     If the constant use of sys stdout write   is a bother it can be be wrapped in a tiny function  or the package turned into a class with methods that set terminal behavior  print ANSI codes    Some of the above is more of a suggestion to look it up  like combining reverse mode and color    This is available in the Perl module used in the question  and is also sensitive to order and similar        A convenient list of escape codes is surprisingly hard to find  while there are many references on terminal behavior and how to control it  The Wiki page on ANSI escape codes has all information but requires a little work to bring it together  Pages on Bash prompt have a lot of specific useful information   Here is another page with straight tables of codes  There is much more out there   This can be used alongside a module like termocolor

A side note  Windows users should run os system  color   first  otherwise you would see some ANSI escape sequences rather than a colored output

Color Console library is comparatively easier to use  Install this library and the following code would help you   from Color Console import   ctext  This will be printed     white     blue   The first argument is the string to be printed  The second argument is the color of  the text and the last one is the background color    The latest version of Color Console allows you to pass a list or dictionary of colors which would change after a specified delay time   Also  they have good documentation on all of their functions   Visit https   pypi org project Color-Console  to know more
