isinstance
(
object, classinfo
)
Return true if the object
argument is an instance
of the classinfo
argument, or of a (direct or indirect)
subclass thereof. Also return true if classinfo
is a type
object and object
is an object of that type. If object
is not a class instance or an object of the given type, the function
always returns false. If classinfo
is neither a class
object nor a type object, it may be a tuple of class or type objects,
or may recursively contain other such tuples (other sequence types are
not accepted). If classinfo
is not a class, type, or
tuple of classes, types, and such tuples, a TypeError
exception is raised. Changed in version
2.2: Support for a tuple of type information was added.

isinstance˵Ã÷ÈçÏÂ:
    isinstance(object, class-or-type-or-tuple) -> bool
   
    Return whether an object is an instance of a class or of a subclass
thereof.
    With a type as second argument, return whether that is the object's
type.
   
The form using a tuple, isinstance(x, (A, B, ...)), is a shortcut
for
    isinstance(x, A) or isinstance(x, B) or ... (etc.).
