Question

How to remove duplicate items from a list using list comprehension? I have following code:

a = [1, 2, 3, 3, 5, 9, 6, 2, 8, 5, 2, 3, 5, 7, 3, 5, 8]
b = []
b =         


        

Answer 1

If you don't mind using a different technique than list comprehension you can use a set for that:

>>> a = [1, 2, 3, 3, 5, 9, 6, 2, 8, 5, 2, 3, 5, 7, 3, 5, 8]
>>> b = list(set(a))
>>> print b
[1, 2, 3, 5, 6, 7, 8, 9]
