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

Curly braces are used for both dictionary and set comprehensions. Which one is created depends on whether you supply the associated value or not, like following (3.4):

>>> a={x for x in range(3)}
>>> a
{0, 1, 2}
>>> type(a)

>>> a={x: x for x in range(3)}
>>> a
{0: 0, 1: 1, 2: 2}
>>> type(a)
