type(object) type(name, bases, dict)

type() function returns the type of the object if you only have the first parameter, and the three parameters return the new type object.

Example:

>>> type(1) 

2. Use the isinstance() function to determine

isinstance()Syntax of the method:

isinstance(object, classinfo)

If the type of the object is the same as the type of parameter two (classinfo), it returns True, otherwise it returns False.

Example:

>>>a = 2 >>> isinstance (a,int) True
