¿Cómo puedo enviar texto en color a la terminal en Python?

Este símbolo sería un gran bloque de color: █ El único problema es que está extendido en ASCII, tal vez puedas hacerlo funcionar usando http://stackoverflow.com/questions/8465226/using-extended-ascii-codes-with-python

Algunos terminales también pueden mostrar caracteres Unicode. Si eso es cierto para su terminal, los caracteres posibles son casi ilimitados.

Esta respuesta llegó bastante tarde, pero me parece que es la mejor… las que se votaron arriba requieren trucos especiales para Windows, mientras que esta simplemente funciona: stackoverflow.com/a/3332860/901641

¿Qué tal stackoverflow.com/a/42528796/610569 usando pypi.python.org/pypi/lazyme ? (descargo de responsabilidad: enchufe desvergonzado)

Esto depende un poco de la plataforma en la que se encuentre. La forma más común de hacer esto es imprimiendo secuencias de escape ANSI. Para un ejemplo simple, aquí hay algo de código de Python de la Scripts de compilación de Blender:

clase bcolors: ENCABEZADO = '\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.

On Linux, you might want to use tput, like so since it results in more portable code.

@Cawas: A real use case for disable is when you pipe the output to a file; while tools like cat may support colors, it is generally better to not print color information to files.

@AlexanderSimko, here’s a ctypes code snippet to enable VT100 support in Windows 10: import ctypes; kernel32 = ctypes.WinDLL('kernel32'); hStdOut = kernel32.GetStdHandle(-11); mode = ctypes.c_ulong(); kernel32.GetConsoleMode(hStdOut, ctypes.byref(mode)); mode.value |= 4; kernel32.SetConsoleMode(hStdOut, mode).

To anyone using the Python example code from the answer: It should be noted that the colors in the range 90-97 and 100-107 are non-standard and, indeed, on my terminal they don’t all give the colors indicated by the variable names. It’s better to use the standard ranges 30-37 and 40-47. Source: en.wikipedia.org/wiki/…

The answer is Colorama for all cross-platform coloring in Python.

It supports Python 3.5+ as well as Python 2.7.

And as of January 2021 it is maintained.

Example screenshot:

Since it’s emitting ANSI codes, does it work on Windows (DOS consoles) if ansi.sys is loaded? support.microsoft.com/kb/101875

Just noticed that as of 13/01/2011, it’s now under MIT license

doesn’t have unittests (unlike colorama) and not updated since 2011

termcolor.COLORS gives you a list of colours

On Windows run os.system('color') first, then the ANSI escape sequences start working.

Girish Oemrawsingh

Print a string that starts a color/style, then the string, and then end the color/style change with '\x1b[0m':

print('\x1b[6;30;42m' + 'Success!' + '\x1b[0m')

Get a table of format options for shell text with the following code:

def print_format_table():
    """
    prints table of formatted text format options
    """
    for style in range(8):
        for fg in range(30,38):
            s1 = ''
            for bg in range(40,48):
                format=";".join([str(style), str(fg), str(bg)]) s1 += '\x1b[%sm %s \x1b[0m' % (format, format)
            print(s1)
        print('\n')

print_format_table()

Reference: https://en.wikipedia.org/wiki/ANSI_escape_code#Colors

This is, in my opinion, the easiest method. As long as you have the RGB values of the color you want, this should work:

def colored(r, g, b, text):
    return f"\033[38;2;{r};{g};{b}m{text}\033[38;2;255;255;255m"

An example of printing red text:

text="Hello, World!"
colored_text = colored(255, 0, 0, text)
print(colored_text)

#or

print(colored(255, 0, 0, 'Hello, World!'))

Multi-colored text

text = colored(255, 0, 0, 'Hello, ') + colored(0, 255, 0, 'World')
print(text)

This is actually the proper answer to the question and should be selected. The question is how to print colours in python and NOT what external libraries can be used.

@mike_rodent This isn’t *nix specific but depends on whether terminal supports ANSI

This can be further tidied using a lambda and f-strings: `coloured = lambda r, g, b, text: f’\033[38;2;{r};{g};{b}m{text} \033[38;2;255;255;255m’

There is a side effect trailing space after the current implementation. You can get rid of by removing the trailing space from the string format. Use this instead: f”\033[38;2;{r};{g};{b}m{text}\033[38;2;255;255;255m”
