Python NameError: globaler Name

Question

Hallo, ich bekomme immer diesen Fehler, wenn ich versuche, die Funktion auszuführen, und Wählen Sie eine Farbe in diesem Fall ist es rosa.

import pygame 

import sys Import-Menü Import rgbcolors aus pygame.locals importieren * von rgbcolors importieren RGBColor

def main():

# start screen 
pygame.init() 
screen1 = pygame.display.set_mode((500, 400)) 

# Fill background 
background = pygame.Surface(screen1.get_size()) 
pygame.draw.line(screen1, (255, 0, 0), (230, 230), (100, 211), 4) 
background = background.convert() 
background.fill((0, 0,0)) 


# Displaying text 
font = pygame.font.Font(None, 36) 
text = font.render("Alien", 23, ((rgbcolor(pink)))) 
textpos = text.get_rect() 
textpos.centerx = background.get_rect().centerx 
background.blit(text, textpos) 

screen1.blit(background, (0, 0)) 
pygame.display.flip() 

while 1: 
    for event in pygame.event.get(): 
     if event.type == QUIT: 
      return 
    screen1.blit(background, (0, 0)) 
    pygame.display.flip() 
    pygame.time.get_ticks() 

if __name__ == "__main__": 
    main() 

und dies ist meine RGBColor Funktion.

def rgbcolor(color): 
    red = (255, 0, 0) 
    green = (0, 255, 0) 
    blue = (0, 0, 255) 
    darkBlue = (0, 0, 128) 
    white = (255, 255, 255) 
    black = (0, 0, 0) 
    pink = (255, 200, 200) 

pass 

Fehlercode.

Versuch mit diesem:

import pygame 
from pygame.locals import * 


def rgbcolor(color): 
    colors = {'red': (255, 0, 0), 'green': (0, 255, 0), 'blue': (0, 0, 255), 
       'darkBlue': (0, 0, 128), 'white': (255, 255, 255), 'black': (0, 0, 0), 
       'pink': (255, 200, 200)} 
    return colors[color] 


def main(): 
    # start screen 
    pygame.init() 
    screen1 = pygame.display.set_mode((500, 400)) 

    # Fill background 
    background = pygame.Surface(screen1.get_size()) 
    pygame.draw.line(screen1, (255, 0, 0), (230, 230), (100, 211), 4) 
    background = background.convert() 
    background.fill((0, 0, 0)) 

    # Displaying text 
    font = pygame.font.Font(None, 36) 
    text = font.render("Alien", 23, rgbcolor('pink')) 
    textpos = text.get_rect() 
    textpos.centerx = background.get_rect().centerx 
    background.blit(text, textpos) 
    screen1.blit(background, (0, 0)) 
    pygame.display.flip() 
    while 1: 
     for event in pygame.event.get(): 
      if event.type == QUIT: 
       return 
     screen1.blit(background, (0, 0)) 
     pygame.display.flip() 
     pygame.time.get_ticks() 


if __name__ == "__main__": 
    main()
