• range()

>>> range(10)
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> range(5,10)
[5, 6, 7, 8, 9]
>>> list(range(0,10,3))
[0, 3, 6, 9]

>>> list(range(10,0,-3))

[10, 7, 4, 1]

range(stop)                0 ≦ i < stop

range(start, stop)          start ≦ i < stop

range(start, stop, step)  start ≦ i < stop

range(stop, start, -step)  stop ≧ i > start

• for()

>>> names = ['pico', 'ted', 'hop']

>>> for i in names:

...      print i

pico

ted

hop

• remove(), del()

>>> names = ['pico', 'ted', 'hop']

>>> names.remove('pico')

>>> names

['ted', 'hop']

>>> names.pop(1)

'hop'

>>> names

['ted']

• random(), uniform(), randrange(), randint()

>>> num = range(5)

>>> num

[0, 1, 2, 3, 4]

>>> random.randint(0, len(nums)-1)
