Yes, it depends how the library was designed. Some are designed so that you
can import some of the library into your global namespace. For example, in
Pygame library, it's accepted to do
import pygame
from pygame.locals import *
This keeps the methods like
pygame.init()
pygame.display.set_mode()
etc.
but it lets you avoid having to do
for event in pygame.event.get():
if event.type == pygame.KEYDOWN and event.key == pygame.K_UP:
instead you can do
for event in pygame.event.get():
if event.type == KEYDOWN and event.key == K_UP:
But I don't know of any case where it's preferable to use the "from" syntax,
it's mostly just a laziness thing.
