ANSI Escape Sequences

Some terminals support the ability to pass in special escape sequences to alter the color, weight, and appearance of the text being printed. These escape sequences are called ANSI escape sequences, named after the ANSI standard that specifies their usage:

def esc(code):
    return f'\033[{code}m'

Here’s what you’ll get:

>>>
>>> print('this is ', esc('31'), 'really', esc(0), ' important', sep='')
this is really important
>>> print('this is ', esc('31;1'), 'really', esc(0), ' important', sep='')
this is really important
>>> print('this is ', esc('31;1;4'), 'really', esc(0), ' important', sep='')
this is really important
