I'm confused about why i get a type error when i call an object's
method. Here's the example code:
>>> class Foo:
def __init__(self):
self.foo = []
def foo(self):
print "in foo!"


>>> f = Foo()
>>> dir(f)
['__doc__', '__init__', '__module__', 'foo']
>>> f.foo()

Traceback (most recent call last):
File "<pyshell#32>", line 1, in <module>
f.foo()
TypeError: 'list' object is not callable
>>>
