I have a python property like this:
class Foo: @property def maxInputs(self): return self._persistentMaxInputs.value @maxInputs.setter def maxInputs(self, value): self._persistentMaxInputs.value = value Currently, the value of maxInputs can be get and set by everyone.
However, I want to allow everyone to get the value of the maxInputs, but it should only be set inside of the Foo class.
So is there a way to declare a property with a private setter and a public getter?
Python has no privacy model. Using underscores is only a convention, there is no access control. If you don't want the 'public' API to include a sett, then just remove the setter from your class and assign to self._persistentMaxInputs.value in your class code directly. You can make it a function if you want to limit the number of locations that need to remember this:
def _setMaxInputs(self, value): self._persistentMaxInputs.value = value You can of course make that a separate property object, but then you'd have to forgo the decorator syntax:
def _maxInputs(self, value): self._persistentMaxInputs.value = value _maxInputs = property(None, _maxInputs) but now at least you can use self._maxInputs = value in your class code. This doesn't really offer that much of a syntax improvement however.
I use two properties in a case where I have a public property with private setter. It does create some redundant code, but I end up following the convention with decorators. See example below:
@property def current_dir(self) -> str: """ Gets current directory, analogous to `pwd` :return: Current working directory """ return self._current_dir @property def _current_dir(self) -> None: return self._current_dir @_current_dir.setter def _current_dir(self, path:str) -> None: self._current_dir = path 
RecursionError because the _current_dir(self) getter method is calling itself (self._current_dir).
