Objects can be made sortable with 'order=True' and immutable with 'frozen=True'. For object to be hashable, all attributes must be hashable and 'frozen' must be True. Function field() is needed because '<attr_name>: list = []' would make a list that is shared among all instances. ...
Constant Value Patterns This is used to match against constants and enum values. Every dotted name in a pattern is looked up using normal Python name resolution rules, and the value is used for comparison by equality with the matching expression (same as for literals). As a special case to...

The Python convention, however, is to capitalize enum values. Reading the attributes of instances of types is done using the corresponding properties: print("vm.name: %s" % vm.name) print("vm.memory: %s" % vm.memory) for custom_property in vm.custom_properties: ... 2.4. Using...
