>>> import random



>>> # 0.0 <= float < 1.0

>>> random.random()

>>> # 10.0 <= float < 20.0

>>> random.uniform(10,20)

>>> # 10 <= int <= 20  (can be 20)

>>> random.randint(10,20)

10



>>> # 10 <= int < 20  (even only, coz step=2)

>>> random.randrange(10,20,2)

16



>>> # choose from a list

>>> random.choice([1, 2, 3, 5, 9])

2



>>> # make a list into random order

>>> cards = range(52)

>>> random.shuffle(cards)  # order is random now

>>> cards[:5]   # get 5 cards
