colouring strings

[newbieAuggie2019]

I would like to say, as these didn’t do what I wanted, that I tried other things:

I tried curses (yeah, I know that I should be fed up by now, but no, it’s not that!!!).

"The curses library supplies a terminal-independent screen-painting and keyboard-handling facility for text-based terminals; such terminals include VT100s, the Linux console, and the simulated terminal provided by X11 programs such as xterm and rxvt."

So once more, problems with Windows …

I used then, curses for windows
https://pypi.org/project/windows-curses/
but I kept not getting the desired results.

I tried pygments with matplot, which curiously didn’t work on the cmder, but did in my Python 3.7.4 Shell, displaying a beautiful butterfly image on matplot (but I want a nice display while I’m learning to code too).



I tried blessed and blessings (data further down). The author of blessings (last release: Jun‎ ‎21‎, ‎2018) is also the co-author of blessed (last release: Jun‎ ‎20‎, ‎2018). Blessed provides a demo program, written in some Python 2, that I managed to adapt to Python 3, but when I ran it, its output was with no formatting and with the following warning:

Error:
C:\Users\User1\AppData\Local\Programs\Python\Python37\lib\site-packages\blessed\terminal.py:32: UserWarning: One or more of the modules: 'termios', 'fcntl', and 'tty' are not found on your platform 'win32'. The following methods of Terminal are dummy/no-op unless a deriving class overrides them: setraw, cbreak, kbhit, height, width
  warnings.warn(_MSG_NOSUPPORT)

That means again, problems due to Windows.

Blessings provides a demo program, written in Python 3, but when I ran it, it produced the following error:

Error:
ModuleNotFoundError: No module named 'fcntl'.

That means again, problems due to Windows.


I kept searching for other solutions, like fabulous 0.3.0 (data further down). I thought it could be great, not only for the hype on the site:

"Fabulous is a Python library (and command line tools) designed to make the output of terminal applications look fabulous. Fabulous allows you to print colors, images, and stylized text to the console (without curses.) Fabulous also offers features to improve the usability of Python’s standard logging system."

https://jart.github.io/fabulous/

but for some images I saw there:



Unfortunately, when I tried to run the demo, the following error message appeared:

Error:
ModuleNotFoundError: No module named 'fcntl'

This error seems to be once again related to Windows operating system:

"Since the fcntl module is for unix(like) systems only, it is unlikely the software works on Windows…"

The proof that these styles (or attributes) can be applied and work is this image, produced in bash (a command processor, for the GNU operating system, typically run in a text window, allowing the user to type commands which cause actions), in urxvt (a customizable terminal emulator) with a Zenburn-style colour scheme (Zenburn is a low-contrast colour scheme):



where you can see 'italic' (\33[3m), 'underline' (\33[4m), 'blinking' (\33[5m), coloured font (\33[33m), and coloured font-background (\33[44m). Nevertheless, I think it is very difficult to appreciate the 'bold' font (\33[1m).
