>>> random.randint(1, 100)
19

>>> random.randrange(0, 100, 2)
22

>>> random.uniform(1, 5.5)
1.633552076031568

>>> random.choice('abcdefghijklmnopqrstuvwxyz!@#$%^&*')
'%'

>>> random.choice(['LOL', 'NDF', 'CF'])
'LOL'

>>> random.sample('abcdefghijklmnopqrstuvwxyz$', 5)
['w', 'm', 'f', 'y', 'o']

>>> random.sample(range(1,11),10)
[3, 10, 8, 9, 5, 2, 7, 1, 6, 4]

>>> '-'.join( random.sample(['z','y','x','w','v','u','t','s','r','q','p','o','n','m','l','k','j','i','h','g','f','e','d','c','b','a'], 6) )

'g-j-x-b-v-k'

>>>i = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>>random.shuffle(i)
>>>i

[2, 6, 8, 0, 7, 5, 1, 4, 9, 3]
