== versus is operators and type()

[Alvaro Figueiredo]

Hi, All.

When dealing with type() function is the same to use == operator and 
'is' operator?

As an example, are the two expressions bellow totally equivalent?

type(arg) is type(0) or type(arg) is type(0.0)

type(arg) in (type(0), type(0.0))

Thanks in advance.
