For the characters  Your terminal most probably uses Unicode  typically UTF-8 encoded  characters  so it s only a matter of the appropriate font selection to see your favorite character  Unicode char U 2588   Full block  is the one I would suggest you use   Try the following   import unicodedata fp  open  character list    w   for index in xrange 65536       char  unichr index      try  its name  unicodedata name char      except ValueError  its name   N A      fp write   05d  04x  s  s n     index  index  char encode  UTF-8    its name  fp close     Examine the file later with your favourite viewer   For the colors  curses is the module you want to use  Check this tutorial

I created a project  console-color  and already published it to PyPI  You can throw pip install console-color to install it  And I write the document with Sphinx-read-the-doc  see here  You can get more example from google-colab  I still post some example to attract the user to click the above link    cprint is something like below   cprint text  str  fore  T RGB   None  bg  T RGB   None  style  Style         where T RGB   Union Tuple int  int  int   str  for example  You can input  255  0  0  or   ff0000  or  ff0000   They are OK    The Style you can input the   Style     the IDE will help you to choose what you wanted     from console color import RGB  Fore  Style  cprint  create print from console color import    cprint  quot Hello  World  quot   RGB RED  RGB YELLOW  Style BOLD Style URL Style STRIKE  cprint  quot Hello  World  quot   fore  255  0  0   bg  quot ffff00 quot   style Style BOLD Style URL Style STRIKE    Of course  you don   t have to enter all the parameters  You can just add the attributes you want   To be honest  this project is not special  It just uses the f quot  033  target  2  r   g   b m text  style  quot  where target is 38 or 48  text is your input string  and style is   33 0m     33 1m        033 9m   Some kind of stuff  And I just make it easy to use  at least for me

I suggest this new library Printy  They just released version 1 2 0 as a cross-platform library  Check it out  Printy on GitHub It is based on flags so you can do stuff like from printy import printy    With global flags  this will apply a bold  B  red  r  color and an underline  U  to the whole text printy  quot Hello  World  quot    quot rBU quot      With inline formats  this will apply a dim  D   blue  b  to the word  Hello  and a stroken  S   yellow  y  to the word  world   and the rest will remain as the predefined format printy  quot this is a  bD Hello   yS world  text quot

There is also the Python termcolor module  Usage is pretty simple  from termcolor import colored  print colored  hello    red    colored  world    green    Or in Python 3  print colored  hello    red    colored  world    green     It may not be sophisticated enough  however  for game programming and the  quot colored blocks quot  that you want to do

For Windows you cannot print to console with colors unless you re using the Win32 API  For Linux it s as simple as using print  with the escape sequences outlined here  Colors For the character to print like a box  it really depends on what font you are using for the console window  The pound symbol works well  but it depends on the font

My favorite way is with the Blessings library  full disclosure  I wrote it   For example   from blessings import Terminal  t   Terminal   print t red  This is red    print t bold bright red on black  Bright red on black     To print colored bricks  the most reliable way is to print spaces with background colors  I use this technique to draw the progress bar in nose-progressive   print t on green        You can print in specific locations as well   with t location 0  5       print t on yellow        If you have to muck with other terminal capabilities in the course of your game  you can do that as well  You can use Python s standard string formatting to keep it readable   print   t clear eol You just cleared a  t bold whole t normal  line   format t t    The nice thing about Blessings is that it does its best to work on all sorts of terminals  not just the  overwhelmingly common  ANSI-color ones  It also keeps unreadable escape sequences out of your code while remaining concise to use  Have fun

To address this problem I created a mind-numbingly simple package to print strings with interpolated color codes  called icolor   icolor includes two functions  cformat and cprint  each of which takes a string with substrings that are interpolated to map to ANSI escape sequences e g   from icolor import cformat   there is also cprint  cformat  This is  RED a red string  partially with a  xBLUE blue background    This is  x1b 31ma red string  partially with a  x1b 44mblue background x1b 0m    All the ANSI colors are included  e g   RED    BLUE   etc    as well as  RESET    BOLD  and others   Background colors have an x prefix  so a green background would be  xGREEN    One can escape   with      Given its simplicity  the best documentation is probably the code itself   It is on PYPI  so one can sudo easy install icolor

This somewhat depends on what platform you are on  The most common way to do this is by printing ANSI escape sequences  For a simple example  here s some Python code from the Blender build scripts  class bcolors      HEADER     033 95m      OKBLUE     033 94m      OKCYAN     033 96m      OKGREEN     033 92m      WARNING     033 93m      FAIL     033 91m      ENDC     033 0m      BOLD     033 1m      UNDERLINE     033 4m   To use code like this  you can do something like  print bcolors WARNING    quot Warning  No active frommets remain  Continue  quot    bcolors ENDC   Or  with Python 3 6   print f quot  bcolors WARNING Warning  No active frommets remain  Continue  bcolors ENDC  quot    This will work on unixes including OS X  Linux and Windows  provided you use ANSICON  or in Windows 10 provided you enable VT100 emulation   There are ANSI codes for setting the color  moving the cursor  and more  If you are going to get complicated with this  and it sounds like you are if you are writing a game   you should look into the  quot curses quot  module  which handles a lot of the complicated parts of this for you  The Python Curses HowTO is a good introduction  If you are not using extended ASCII  i e   not on a PC   you are stuck with the ASCII characters below 127  and     or     is probably your best bet for a block  If you can ensure your terminal is using a IBM extended ASCII character set  you have many more options  Characters 176  177  178 and 219 are the  quot block characters quot   Some modern text-based programs  such as  quot Dwarf Fortress quot   emulate text mode in a graphical mode  and use images of the classic PC font  You can find some of these bitmaps that you can use on the Dwarf Fortress Wiki see  user-made tilesets   The Text Mode Demo Contest has more resources for doing graphics in text mode

I wrote a simple module  available at  http   pypi python org pypi colorconsole  It works with Windows  Mac OS X and Linux  It uses ANSI for Linux and Mac  but native calls to console functions on Windows  You have colors  cursor positioning and keyboard input  It is not a replacement for curses  but can be very useful if you need to use in simple scripts or ASCII games

I suggest this new library Printy  They just released version 1 2 0 as a cross-platform library  Check it out  Printy on GitHub It is based on flags so you can do stuff like from printy import printy    With global flags  this will apply a bold  B  red  r  color and an underline  U  to the whole text printy  quot Hello  World  quot    quot rBU quot      With inline formats  this will apply a dim  D   blue  b  to the word  Hello  and a stroken  S   yellow  y  to the word  world   and the rest will remain as the predefined format printy  quot this is a  bD Hello   yS world  text quot

This somewhat depends on what platform you are on  The most common way to do this is by printing ANSI escape sequences  For a simple example  here s some Python code from the Blender build scripts  class bcolors      HEADER     033 95m      OKBLUE     033 94m      OKCYAN     033 96m      OKGREEN     033 92m      WARNING     033 93m      FAIL     033 91m      ENDC     033 0m      BOLD     033 1m      UNDERLINE     033 4m   To use code like this  you can do something like  print bcolors WARNING    quot Warning  No active frommets remain  Continue  quot    bcolors ENDC   Or  with Python 3 6   print f quot  bcolors WARNING Warning  No active frommets remain  Continue  bcolors ENDC  quot    This will work on unixes including OS X  Linux and Windows  provided you use ANSICON  or in Windows 10 provided you enable VT100 emulation   There are ANSI codes for setting the color  moving the cursor  and more  If you are going to get complicated with this  and it sounds like you are if you are writing a game   you should look into the  quot curses quot  module  which handles a lot of the complicated parts of this for you  The Python Curses HowTO is a good introduction  If you are not using extended ASCII  i e   not on a PC   you are stuck with the ASCII characters below 127  and     or     is probably your best bet for a block  If you can ensure your terminal is using a IBM extended ASCII character set  you have many more options  Characters 176  177  178 and 219 are the  quot block characters quot   Some modern text-based programs  such as  quot Dwarf Fortress quot   emulate text mode in a graphical mode  and use images of the classic PC font  You can find some of these bitmaps that you can use on the Dwarf Fortress Wiki see  user-made tilesets   The Text Mode Demo Contest has more resources for doing graphics in text mode

To address this problem I created a mind-numbingly simple package to print strings with interpolated color codes  called icolor   icolor includes two functions  cformat and cprint  each of which takes a string with substrings that are interpolated to map to ANSI escape sequences e g   from icolor import cformat   there is also cprint  cformat  This is  RED a red string  partially with a  xBLUE blue background    This is  x1b 31ma red string  partially with a  x1b 44mblue background x1b 0m    All the ANSI colors are included  e g   RED    BLUE   etc    as well as  RESET    BOLD  and others   Background colors have an x prefix  so a green background would be  xGREEN    One can escape   with      Given its simplicity  the best documentation is probably the code itself   It is on PYPI  so one can sudo easy install icolor
