A simple DEMO to show how to enhance Python inside a Terminal. This works on Classic AMIGAs, E-UAE, Debian Linux 6.0.0, PCLinuxOS 2009, Windows XP and Vista and WinUAE, from Python 1.4.0 to 3.3A2.

Due to a complaint about my _fun_ upload recently I decided to post this so that the MANY can now find out how to manipulate text inside a Python Terminal window so that it looks much better.

Read the code for more information...

# Colours.py
#
# This DEMO script prints colours and codes for Linux, Classic AMIGA and Windows Python.
#
# This is Public Domain and you may do with it as you please.
#
# Tested on standard classic AMIGA A1200(HD), E-UAE, Debian Linux, Windows XP and Vista,
# and WinUAE from Python 1.4.0 to 3.3A2.
#
# This shows how to enhance text printouts to the screen for better presentation.
# Windows is limited to a complete switch of the whole window to only foreground
# and background. The AMIGA and derivatives are limited to ONLY the first eight
# WorkBench colours. Linux is unable to do ITALICS reliably on various terminal
# programs using the escape mode method...
#
# Because of a fun program I uploaded that was voted down I decided to upload this
# because although some may know about it, MANY won't! I will say no more about the fun
# program. This does NOT do anything to your personal Terminal setups except display
# various modes and colours at the flick of a simple escape sequence.
#
# Copy/drag this file to the Lib(rary) directory/folder/drawer, rename to Colours.py
# and run from the Python Prompt using:-
#
# >>> import Colours<RETURN/ENTER>
#
# And away you go...

This code was prompted by a complaint about my fun demo upload. I expect professionals to know about this but amateurs not so, so this is the result.

Apologies if there are any typos in the comments. The code is self explanatory...

To the person who voted this up on 13-04-2012, you know who you are, many thanks from this mere amateur...

Again many thanks...

So that's it. What am I supposed to do with it?

Do I need to add \033[0;34;47m Blue \033[0m 0;34;47m around the text I want it to be blue?

If you can wrap them up, let people just add \blue text you want it to be blue here so they can get colorful result.

That would be so damn good.

colours == Esc[attribute;forground;backgroundm reset == Esc[0m

colours, normal green on black:-

c="\033[0;40;32m"

reset to default Terminal mode:-

r="\033[om"

Test text for line below...

x="green"

For all versions of Python in Linux...

print("The word "+c+x+r+" will be green on black..."

;o)

Dunno how the text came out like that but "r" is wrong...

r="\033[0m"

Also the print routine is wrong... :/

print("The word "+c+x+r+" will be green on black...")

is correct...

Maybe I ought to go back to bed and get out of the other side... ;oO

The following code is a functional example of a blue user prompt that captures a normal text response, on the same line. This was tested in Python 2.7.3 on Fedora 16, and with Python 2.7.1 on OS X Lion (10.7.4).

bluestr  = "\033[1;34m"
normstr = "\033[1;m"

print bluestr + "Enter Principal Amount: " + normstr,
principal = float(raw_input())
print principal
