Because you are checking if the type object dict is equal to the str object
"<type 'dict'>". A type object will never compare equal to a str object,
even though the string representation of them is the same.
>>> type({}) == "<type 'dict'>"
False
>>> type({})
<type 'dict'>
>>> str(type({})) == "<type 'dict'>"
True
>>> type({}) == dict
True
>>> platform.__builtins__.__class__ == dict
True
