Simple way to display text on screen in Python?

Question

I\'ve been googling and looking through StackOverflow but no luck...

What I would like is to display text to the screen (not console) for an art project I am develop

Here's a pygame solution. Just pass the random letters and color to Font.render and then blit the returned surface. To center it I call the get_rect method of the txt surface and pass the center of the screen_rect as the center argument. Note that you can't choose a different color for each letter. To do that you would probably have to render several "one letter" surfaces and then combine them.

Epilepsy warning - The text was getting changed really quickly (each frame (30 fps)) and I wasn't sure if that could cause epileptic seizures, so I added a timer to update the text only every 10 frames. Be careful if you want to increase the update speed.

import sys
from random import choice, randrange
from string import ascii_letters

import pygame as pg


def random_letters(n):
    """Pick n random letters."""
    return ''.join(choice(ascii_letters) for _ in range(n))


def main():
    info = pg.display.Info()
    screen = pg.display.set_mode((info.current_w, info.current_h), pg.FULLSCREEN)
    screen_rect = screen.get_rect()
    font = pg.font.Font(None, 45)
    clock = pg.time.Clock()
    color = (randrange(256), randrange(256), randrange(256))
    txt = font.render(random_letters(randrange(5, 21)), True, color)
    timer = 10
    done = False

    while not done:
        for event in pg.event.get():
            if event.type == pg.KEYDOWN:
                if event.key == pg.K_ESCAPE:
                    done = True

        timer -= 1
        # Update the text surface and color every 10 frames.
        if timer <= 0:
            timer = 10
            color = (randrange(256), randrange(256), randrange(256))
            txt = font.render(random_letters(randrange(5, 21)), True, color)

        screen.fill((30, 30, 30))
        screen.blit(txt, txt.get_rect(center=screen_rect.center))

        pg.display.flip()
        clock.tick(30)


if __name__ == '__main__':
    pg.init()
    main()
    pg.quit()
    sys.exit()
