Name
isinstance
Synopsis
isinstance(obj,cls)
Returns True when obj
is an instance of class cls (or any
subclass of cls) or when
cls is a type object and
obj is an object of that type. Otherwise
it returns False.
Since Python 2.2.1, cls can also be a
tuple whose items are classes or types. In this case,
isinstance returns True if
obj is an instance of any of the items of
tuple cls, otherwise
isinstance returns False.
