Python has inbuilt 'random' package to do this.
To get one random item from the list:
>>> import random
>>> items = ['a', 'b', 'c', 'd', 'e', 'f', 'g']
>>> print random.choice(items)
'c'
There’s an equally simple way to select n items from the sequence:
>>> import random
>>> items = ['a', 'b', 'c', 'd', 'e', 'f', 'g']
>>> print random.sample(items, 2)
['e', 'a']
