How do I print colored output with Python 3?

It is very simple with colorama, just do this:

import coloramafrom colorama import Fore, Styleprint(Fore.BLUE + "Hello World")

And here is the running result in Python3 REPL:

And call this to reset the color settings:

print(Style.RESET_ALL)

To avoid printing an empty line write this:

print(f"{Fore.BLUE}Hello World{Style.RESET_ALL}")

Here's a class of mine I use to color specific output in Python 3 scripts. You could import the class and use like so:from colorprint import ColorPrint as __.print_fail('Error occurred, quitting program')

import sys# Colored printing functions for strings that use universal ANSI escape sequences.# fail: bold red, pass: bold green, warn: bold yellow, # info: bold blue, bold: bold whiteclass ColorPrint:    @staticmethod    def print_fail(message, end = '\n'):        sys.stderr.write('\x1b[1;31m' + message.strip() + '\x1b[0m' + end)    @staticmethod    def print_pass(message, end = '\n'):        sys.stdout.write('\x1b[1;32m' + message.strip() + '\x1b[0m' + end)    @staticmethod    def print_warn(message, end = '\n'):        sys.stderr.write('\x1b[1;33m' + message.strip() + '\x1b[0m' + end)    @staticmethod    def print_info(message, end = '\n'):        sys.stdout.write('\x1b[1;34m' + message.strip() + '\x1b[0m' + end)    @staticmethod    def print_bold(message, end = '\n'):        sys.stdout.write('\x1b[1;37m' + message.strip() + '\x1b[0m' + end)

Put these classes into Color.py file near your test.py file and run test.py.I've tested these classes on Ubuntu Server 16.04 and Linux Mint 18.2 . All classes worked very good except GColor (RGB), that, it is usable in graphical terminal like Linux Mint terminal.Also, you can use these classes like this:

print(Formatting.Italic + ANSI_Compatible.Color(12) + "This is a " + Formatting.Bold + "test" + Formatting.Reset_Bold +  "!" + ANSI_Compatible.END + Formatting.Reset)print(Color.B_DarkGray + Color.F_LightBlue + "This is a " + Formatting.Bold + "test" + Formatting.Reset_Bold +  "!" + Base.END)

Result:

Note: It's not working on Windows!

File Color.py :

And,

File test.py:

from Color import *if __name__ == '__main__':    print("Base:")    print(Base.FAIL,"This is a test!", Base.END)    print("ANSI_Compatible:")    print(ANSI_Compatible.Color(120),"This is a test!", ANSI_Compatible.END)    print("Formatting:")    print(Formatting.Bold,"This is a test!", Formatting.Reset)    print("GColor:") # Gnome terminal supported    print(GColor.RGB(204,100,145),"This is a test!", GColor.END)    print("Color:")    print(Color.F_Cyan,"This is a test!",Color.F_Default)
