如何在python中将集合转换为列表?

问题描述：

我正在尝试将一组转换为Python 2.6中的列表.我正在使用以下语法:

I am trying to convert a set to a list in Python 2.6. I'm using this syntax:

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

但是，我得到了以下堆栈跟踪:

However, I get the following stack trace:

Traceback (most recent call last):
  File "<console>", line 1, in <module>
TypeError: 'set' object is not callable

我该如何解决?

答

已经是列表

type(my_set)
>>> <type 'list'>

您是否想要

my_set = set([1,2,3,4])
my_list = list(my_set)
print my_list
>> [1, 2, 3, 4]

您的最后评论的输出

>>> 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]

我想知道你是否做了这样的事情:

I'm wondering if you did something like this :

>>> set=set()
>>> set([1,2])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'set' object is not callable
