How to convert a set to a list in python?

Question

In python 2.6, When I tried to convert a set to a list using the below code:

first_list = [1,2,3,4]

my_set=set(first_list)

my_list = list(my_set)

I'm getting error like this:

Traceback (most recent call last):

  File "<console>", line 1, in <module>

TypeError: 'set' object is not callable

Can anyone suggest to me some ways to fix this?

Answer 1

If you check the type of my_set, it's already a list

type(my_set)

>>> <type 'list'>

Are you expecting like this:

my_set = set([1,2,3,4])

my_list = list(my_set)

print my_list

>> [1, 2, 3, 4] 

This is the output of your last comment

>>> my_list = [1,2,3,4]

>>> my_set = set(my_list)

>>> my_new_list = list(my_set)

>>> print my_new_list

[1, 2, 3, 4]

I'm still thinking if you've done like this:

>>> set=set()

>>> set([1,2])

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

TypeError: 'set' object is not callable
