What is faster, a for loop using enumerate or using xrange?
EDIT: I have tested, and I just see minimal differences.
Enumerate is slightly faster. Tested in Python 3:
>>>import pygame
>>>pygame.init()
>>>clock = pygame.time.Clock()
>>>a = list(range(100000))
>>>def do_with_range():
... clock.tick()
... k = 0
... for i in range(len(a)):
... k += a[i]
... print(clock.tick())
>>>def do_with_enumerate():
... clock.tick()
... k = 0
... for i, j in enumerate(a):
... k += j
... print(clock.tick())
>>>do_with_range()
23
>>>do_with_enumerate()
21
If a wouldn't be a list, but a generator, it would be significantly faster to use enumerate (74ms using range, 23ms using enumerate).
