How to make a string’s content appears on screen as we type on keyboard?

I have this function, where player can type his name, but I want each letter to appear on the screen as he types them.
Here is my function :

def input_player_name():
    player_name_screen = True
    name = ""
    win.blit(player_name_bg, (0, 0))
    while player_name_screen:
        for event in pygame.event.get():
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_RETURN:
                    print(name)
                    player_name_screen = False
                else:
                    name += event.unicode                 
        pygame.display.update()
        clock.tick(fps)

If I write print(name)right after name+=event.unicode, each thing typed appears in the console. Do I have to use something like this

textsurface = game_font.render(str(name), False, (255, 255, 255))
    win.blit(textsurface, (0, 0))

and make it update each time something new goes into name?
Thanks for your help

Method 1

You can either use pygame.font or pygame.freetype. In the following I use
pygame.font.
Waht you have to do is to generate a font object and render the text to a pygame.Surface (name_surf). This surface has to be blit to the window continuously in the loop. When the name changes, the the surface has to be recreated:

import pygame
import pygame.font

pygame.init()

win = pygame.display.set_mode((500, 200))
clock = pygame.time.Clock()
fps = 60

def input_player_name():
    # create font and text surface
    font = pygame.font.SysFont(None, 100)
    name_surf = font.render('', True, (255, 0, 0))
    player_name_screen = True
    name = ""
    while player_name_screen:
        for event in pygame.event.get():
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_RETURN:
                    player_name_screen = False
                else:
                    name += event.unicode
                    # recreate text surface   
                    name_surf = font.render(name, True, (255, 0, 0))              

        win.blit(player_name_bg, (0, 0))
        # blit text to window
        win.blit(name_surf, (50, 50))
        pygame.display.update()
        clock.tick(fps)

input_player_name()
