Python standard library: Built-in function isinstance (object, ClassInfo)

This function is used to determine If an object instance is an instance of class ClassInfo , and if it is True, returns False. The parameter ClassInfo can be a type, or it can be a type such as Tuple/dict/list.

Example:

#isinstance () class Fooa:    passclass Foob (FOOA):    passclass FOOC:    pass    a = Fooa () b = Foob () c = FOOC ()    Print (Isinstance (A, FOOA)) print (Isinstance (A, Foob)) print (Isinstance (b, Fooa)) print (Isinstance (b, Foob)) print ( Isinstance (c, Fooa)) print (Isinstance (c, Foob)) print (Isinstance ([], list))

The resulting output is as follows:

True

False

True

True

False

False

True
