python - Can someone please explain this weird Pygame importing convention?

Question

I see that people usually import Pygame like this:

import pygame
from pygame.locals import *

I don't understand what's the second line for. If we already imported the whole of Pygame, why import pygame.locals? Doesn't Pygame already include it once it's imported?

Answer 1

import pygame

imports the pygame module into the "pygame" namespace.

from pygame.locals import *

copys all names in pygame.locals into your current namespace. This is not neccessary, but saves you typing.
