PyGame : First interface - part 7.

Today I will start with another feature: add text from the keyboard.
The interface needs to be filled with text and a good way is to read the keyboard.
My example using this feature and print the text into one row and let you erase chars when you typing.
First, you need to know I used python version 2.7.13 and the last pygame version 1.9.2.0a from here.
I used also the PyCharm version Community Edition 2017.1.3.
Let see the source code for this example:
import pygame
from pygame.locals import *

def name():
    pygame.init()
    screen = pygame.display.set_mode((480, 360))
    name = ""
    font = pygame.font.Font(None, 50)
    while True:
        for evt in pygame.event.get():
            if evt.type == KEYDOWN:
                if evt.unicode.isalpha():
                    name += evt.unicode
                elif evt.key == K_BACKSPACE:
                    name = name[:-1]
                elif evt.key == K_SPACE:
                    name = name+str(" ")
            elif evt.type == QUIT:
                return
        screen.fill((0, 0, 0))
        block = font.render(name, True, (255, 255, 255))
        rect = block.get_rect()
        rect.center = screen.get_rect().center
        screen.blit(block, rect)
        pygame.display.flip()

if __name__ == "__main__":
    name()
The result of this python script can see into image below:
