This week’s exercise is going to be revisiting an old exercise 
(see Exercise 5), except require the solution in a different way.

Take two lists, say for example these two:

	a = [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89]
	b = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]
and write a program that returns a list that contains only the elements that 
are common between the lists (without duplicates). Make sure your program works 
on two lists of different sizes. Write this in one line of Python using at 
least one list comprehension. (Hint: Remember list comprehensions from Exercise 
7).

The original formulation of this exercise said to write the solution using one 
line of Python, but a few readers pointed out that this was impossible to do 
without using sets that I had not yet discussed on the blog, so you can either 
choose to use the original directive and read about the set command in Python 
3.3, or try to implement this on your own and use at least one list 
comprehension in the solution.

Extra:

Randomly generate two lists to test this
"""

import random

a = random.sample(range(30), 12)
b = random.sample(range(30), 20)

print (a)

print(b)

print(list(set([item for item in a if item in b])))
