Python Mapping for Dictionaries

Here is the definition of our EmployeeMap once more:

dictionary<long, Employee> EmployeeMap;

As for sequences, the Python mapping does not create a separate named type for this definition. Instead, all dictionaries are simply instances of Python's dictionary type. For example:

em = {}

e = Employee()
e.number = 31
e.firstName = "James"
e.lastName = "Gosling"

em[e.number] = e

The Ice run time validates the elements of a dictionary to ensure that they are compatible with the declared type; a ValueError exception is raised if an incompatible type is encountered.
