How to set up input_box in pygame?

Question

Python

Hello. I am writing a game like alien invasion for self-practice. The player shoots at the alien fleet, if at least one alien collides with the player's ship, or reaches the edge of the screen, the number of available lives decreases. So, when all the lives are used up, the scores for the killed aliens should appear on the screen, and at the bottom of the scores I wanted to implement an input_box in which the player could write his name to then display it in the list of records. I was able to display the input_box on the screen, but it doesn't respond to typing. Tell me, what is the reason, how to fix it?

the code below will work when the aliens reach the edge or when they collide with the ship, when all lives are used up, else will work

def ship_hit(ship, aliens, bullets, stats, screen, settings, sb, play_button, settings_button, scores_button, exit_button, input_box):
    if stats.ships_left > 0:
        stats.ships_left -= 1

        ship.center_ship()

        aliens.empty()
        bullets.empty()
        create_aliens_fleet(screen, settings, aliens, sb, stats)
    else:
        score_label = Button(screen, "Your score:{}".format(stats.score), screen.get_rect().width, 150) # background for score message
        score_label.rect.center = screen.get_rect().center
        score_label.msg_image_rect.center = score_label.rect.center # positioning score message in center of screen/label
        score_label.draw_button()
        input_box.input_box.top = score_label.msg_image_rect.bottom # positioning input_box under score message
        input_box.text_surface_rect = input_box.text_surface.get_rect()
        input_box.text_surface_rect.center = screen.get_rect().center
        input_box.blitme()
        # calling check_events to check pressed buttons and type text in input_box
        check_events(ship, bullets, screen, settings, stats, play_button, settings_button, scores_button, exit_button, sb, aliens, input_box)
        pygame.display.flip()
        sleep(5) # to give player time for typing, how to make it wait till user presses enter button?
        stats.game_active = False


        sleep(1)

check_events

def check_events(ship, bullets, screen, settings, stats, play_button, settings_button, scores_button, exit_button, sb, aliens, input_box):
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()
        elif event.type == pygame.MOUSEBUTTONDOWN:
            mouse_x, mouse_y = pygame.mouse.get_pos()
            check_buttons(mouse_x, mouse_y, play_button, settings_button, scores_button, exit_button, stats, sb, screen, settings, aliens)
            if input_box.input_box.collidepoint(event.pos) and stats.ships_left <0: # collision with input_box
                input_box.active = True # Start typing text in input_box
        if event.type == pygame.KEYDOWN:
            if input_box.active:
                if event.key == pygame.K_BACKSPACE:
                    input_box.text = input_box.text[:-1] # clear last symbol from text
                else:
                    input_box.text += event.unicode # print letters
            if stats.game_active:
                # works when game started
                check_keydown_events(event, ship, bullets, screen, settings, stats)
        elif event.type == pygame.KEYUP:
            check_keyup_events(event, ship)

class Input_box

import pygame
from pygame import color

class Input_text():

    def __init__(self, screen):
        self.screen = screen
        self.font = pygame.font.Font(None, 48)
        self.input_box = pygame.Rect(0, 0, 140, 32)
        self.color_inactive = pygame.Color('lightskyblue3') # border color when not activated typing
        self.color_active = pygame.Color('dodgerblue2') # border color when activated typing
        self.color = self.color_inactive
        self.active = False
        self.text = ''
        self.text_surface = self.font.render(self.text, True, self.color)

    def blitme(self):
        width = max(200, self.text_surface.get_width()+10) # make input_box wider if text is long
        self.input_box.w = width
        self.screen.blit(self.text_surface, (self.input_box.x+5, self.input_box.y+5))
        pygame.draw.rect(self.screen, self.color, self.input_box, 2)

Thanks in advance for your time
