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:
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:
set([0, 1, 2, 3, 5, 10, 11])
7
9
On iPython-Macbook, my output is:
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-29-cd060f1b0bde> in <module>()
1 my_list = [1, 2, 3, 0, 5, 10, 11, 1, 5]
2 your_list = [1, 2, 3, 0, 12, 13]
----> 3 my_set = set(my_list)
4 your_set = set(your_list)
5 print my_set
TypeError: 'set' object is not callable
Additionally, these are the installation details, if relevant: 1. iPython on AWS Micro Instance: https://i.sstatic.net/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.
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-in function set .
Example of this issue occuring -
>>> 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>
TypeError: 'set' object is not callable
