为什么无法将集合转换为列表

Question

为什么无法将集合转换为列表：

一下是代码：
import random

list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
slice = random.sample(list, 5) #从list中随机获取5个元素，作为一个片断返回
set1 = set(list)
set2 = set(slice)
set3 = set(set1^set2)
listx=list(set3)
print(slice)
print(set1^set2)
print(set3)

显示错误：

TypeError Traceback (most recent call last)
in
6 set2 = set(slice)
7 set3 = set(set1^set2)
----> 8 listx=list(set3)
9 print(slice)
10 print(set1^set2)

TypeError: 'list' object is not callable

把list修改为list1，否则和list转换冲突了。
import random

list1 = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
slice = random.sample(list1, 5)
set1 = set(list1)
set2 = set(slice)
set3 = set(set1^set2)
listx=list(set3)
print(slice)
print(set1^set2)
print(set3)
