Why must the text be a unicode?

Question

Why this code is not working?

font = pygame.font.SysFont(None, 24)
zahl = 99
img = font.render(("zahl  ",str(zahl)), True, WHITE)
screen.blit(img, (20, 20))enter code here

I get the message: TypeError: text must be a unicode or bytes

Best regards Joachim

("zahl ",str(zahl)) is a tuple. render expects either a string or a bytes instance. Try this:

img = font.render("zahl  " + str(zahl), True, WHITE)
