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 + "Warning: No active frommets remain. Continue?" + bcolors.ENDC)
Or, with Python 3.6+:
print(f"{bcolors.WARNING}Warning: No active frommets remain. Continue?{bcolors.ENDC}")
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 "curses" 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 "block characters".
Some modern text-based programs, such as "Dwarf Fortress", 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.
figure
tells you the call signature:
from matplotlib.pyplot import figure
figure(figsize=(8, 6), dpi=80)
figure(figsize=(1,1))
would create an inch-by-inch image, which would be 80-by-80 pixels unless you also give a different dpi argument.

To get Tkinter input from the text box, you must add a few more attributes to the normal
.get()
function. If we have a text boxmyText_Box
, then this is the method for retrieving its input.The first part,
"1.0"
means that the input should be read from line one, character zero (ie: the very first character).END
is an imported constant which is set to the string"end"
. TheEND
part means to read until the end of the text box is reached. The only issue with this is that it actually adds a newline to our input. So, in order to fix it we should changeEND
toend-1c
(Thanks Bryan Oakley) The-1c
deletes 1 character, while-2c
would mean delete two characters, and so on.
