- How does the @property decorator work in Python?
temperature = property(get_temperature,set_temperature) could have been broken down as, # make empty property temperature = property() # assign fget temperature = temperature getter(get_temperature) # assign fset temperature = temperature setter(set_temperature) Point To Note: get_temperature remains a property instead of a method
- angular - Property . . . has no initializer and is not definitely . . .

- Whats the pythonic way to use getters and setters?
def set_property(property,value): def get_property(property): Firstly, the above doesn't work, because you don't provide an argument for the instance that the property would be set to (usually self ), which would be:
- Overriding fields or properties in subclasses - Stack Overflow
Use an abstract Property and override it on the inherited classes This benefits from being enforced (you have to override it) and it is clean But, it feels slightly wrong to return a hard-code value rather than encapsulate a field and it is a few lines of code instead of just
