"TypeError: 'set' object is not callable"
提问by user2762934
I have two iPython notebook installations. One on an AWS Micro Instance, the second using Anaconda on my Macbook (OS X Yosemite). I encountered a difference in the way both of them handle the following code:
我有两个 iPython 笔记本安装。一个在 AWS 微型实例上，第二个在我的 Macbook (OS X Yosemite) 上使用 Anaconda。我在他们处理以下代码的方式上遇到了差异：
my_list = [1, 2, 3, 0, 5, 10, 11, 1, 5]
your_list = [1, 2, 3, 0, 12, 13]
my_set = set(my_list)
your_set = set(your_list)
print my_set
print len(my_set)
print len(my_list)
On iPython-AWS, my output is:
在 iPython-AWS 上，我的输出是：
set([0, 1, 2, 3, 5, 10, 11])

On iPython-Macbook, my output is:
在 iPython-Macbook 上，我的输出是：

TypeError Traceback (most recent call last)

----> 3 my_set = set(my_list)

Additionally, these are the installation details, if relevant: 1. iPython on AWS Micro Instance: http://i.stack.imgur.com/qYrq8.png

I cannot seem to find the reason for this difference, although I did come across many threads on Stackoverflow regarding the "TypeError: 'set' object is not callable" issue. I will appreciate any help in understanding why this is so, and if there is anything I can do to ensure my code runs on both installations.
我似乎无法找到这种差异的原因，尽管我确实在 Stackoverflow 上遇到了许多关于“TypeError: 'set' object is not callable”问题的线程。我将不胜感激任何帮助理解为什么会这样，如果我能做些什么来确保我的代码在两个安装上运行。

This error indicates that you may have defined a set with the variable name as set, if you did so, that would overwrite the built-infunction set.
此错误表明您可能定义了一个变量名为 的集合set，如果这样做，将覆盖built-in函数set。
Example of this issue occuring -
发生此问题的示例 -
>>> set = set([1,2,3,4,5])
>>> my_set = set([2,3,4,5,6])
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

Simply remove any predefined variable you have assigned, may be intentionally or unintentionally & the error will be vanished.
I have wrongly placed = signbetween print statement & brackets like print=(A|B);due to which it was happening.
After clearing print variable it was fine.
只需删除您分配的任何预定义变量，可能是有意或无意的，错误就会消失。我错误地placed = sign在打印语句和括号之间print=(A|B);，因为它正在发生。清除打印变量后就好了。
