How to use text in pygame

font = pygame.font.Font('freesansbold.ttf', 32)
text = font.render(text, True, textColor, backgroundColor)
textRect = text.get_rect()
textRect.center = (x,y)
screen.blit(text, textRect)
pygame.display.update()

import pygame
pygame.init()
window = pygame.display.set_mode((500, 500)) 

def set_text(string, coordx, coordy, fontSize): #Function to set text

    font = pygame.font.Font('freesansbold.ttf', fontSize) 
    #(0, 0, 0) is black, to make black text
    text = font.render(string, True, (0, 0, 0)) 
    textRect = text.get_rect()
    textRect.center = (coordx, coordy) 
    return (text, textRect)

window.fill((255, 255, 255)) #Fills the whole window with white
#Places "Text in Pygame!" with an x,y coord of 250, 250 and 60 font size
totalText = set_text("Text in Pygame!", 250, 250, 60)
window.blit(totalText[0], totalText[1])
