List comprehension vs set comprehension

Question

I have the following program. I am trying to understand list comprehension and set comprehension:

mylist = [i for i in range(1,10)]
print(mylist)

clist = []         


        

Answer 1

Set is an unordered, mutable collection of unrepeated elements.

In python you can use set() to build a set, for example:

set>>> set([1,1,2,3,3])
set([1, 2, 3])
>>> set([3,3,2,5,5])
set([2, 3, 5])

Or use a set comprehension, like a list comprehension but with curly braces:

>>> {x for x in [1,1,5,5,3,3]}
set([1, 3, 5])
