Output:

Is it possible to print `traceback.format_exc()` in color using colored

colored_traceback looks useful, but I think it’s overkill for your goal. You can achieve the desired effect with the pygments library and a few lines of code:

import traceback

from pygments import formatters, highlight, lexers


try:
    a = 1 / 0
except:
    tb_text = "".join(traceback.format_exc())

    lexer = lexers.get_lexer_by_name("pytb", stripall=True)
    formatter = formatters.get_formatter_by_name("terminal256")
    tb_colored = highlight(tb_text, lexer, formatter)

    print(tb_colored)
