How to save flappy bird (made with pygame on python 3.9) scores into sql database

I m new to pygame and started learning it by making flappy bird by watching tutorials. I need to save the player's name and score to the sql database ( the table already has been created by me to store data) for a project. But whenever the program comes to saving the name and score, the GUI gets hanged rather than restarting the game and the data doesn't get saved. Here's the code:-

import pygame, sys, random
def sql():
    import mysql.connector as c
    m=c.connect(host="localhost",user="root",password= "password",database="flappy 
bird")
    my=m.cursor()
    n=input('enter your name')
    r = score
    my.execute("insert into table(name, score) values({},'{}')".format(n,r))
    m.commit()
    my.execute("select * from table")
    for i in my:
      print(i)

    random_pipe_pos = random.choice(pipe_height)
    bottom_pipe = pipe_surface.get_rect(midtop = (700,random_pipe_pos))
    top_pipe = pipe_surface.get_rect(midbottom = (700,random_pipe_pos - 300))
    return bottom_pipe,top_pipe

def move_pipes(pipes):
    for pipe in pipes:
        pipe.centerx -= 5
    visible_pipes = [pipe for pipe in pipes if pipe.right > -50]
    return visible_pipes

def draw_pipes(pipes):
    for pipe in pipes:
        if pipe.bottom >= 1024:
            screen.blit(pipe_surface,pipe)

            flip_pipe = pygame.transform.flip(pipe_surface,False,True)
            screen.blit(flip_pipe,pipe)

   pygame.display.update()
   clock.tick(120)

please tell how to solve this. Thank you!

As commenters have pointed out, calling input() will block your program from processing events, so the operating system will think your program has frozen.

To achieve your goals with minimal redesign, you can incorporate the built-in tkinter dialogs to obtain a user name instead of using input(). The application will still block, but your operating system won't think it is non-responsive.

import tkinter
import tkinter.simpledialog

def prompt_username():
    """Create a Tk file dialog and cleanup when finished"""
    top = tkinter.Tk()
    top.withdraw()  # hide window
    user_name = tkinter.simpledialog.askstring(
        "Name?", "What is your name?", parent=top
    )
    top.destroy()
    return user_name

In your sql() function, replace n=input('enter your name') with n = prompt_username(). Although you could do yourself a favour and use variable names with more than one character.

You'll see a dialog like this:

Username dialog
