Python set to list

Question

How can I convert a set to a list in Python? Using

a = set([\"Blah\", \"Hello\"])
a = list(a)

doesn\'t work. It gives me:

You've shadowed the builtin set by accidentally using it as a variable name, here is a simple way to replicate your error

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

The first line rebinds set to an instance of set. The second line is trying to call the instance which of course fails.

Here is a less confusing version using different names for each variable. Using a fresh interpreter

>>> a=set()
>>> b=a()
Traceback (most recent call last):
  File "", line 1, in 
TypeError: 'set' object is not callable

Hopefully it is obvious that calling a is an error
