How to print colored text in Python

Question

How can I output colored text to the terminal in Python?

Answer 1

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 Python3.6+:

print(f"{bcolors.WARNING}Warning: No active frommets remain. Continue?{bcolors.ENDC}")
