Python set to list
Your code does work (tested with cpython 2.4, 2.5, 2.6, 2.7, 3.1 and 3.2):
>>> a = set(["Blah", "Hello"])>>> a = list(a) # You probably wrote a = list(a()) here or list = set() above>>> a['Blah', 'Hello']
Check that you didn't overwrite list
by accident:
>>> assert list == __builtins__.list
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 "<stdin>", line 1, in <module>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 "<stdin>", line 1, in <module>TypeError: 'set' object is not callable
Hopefully it is obvious that calling a
is an error
