Preferred way of defining properties in Python: property decorator or lambda?

Question

Which is the preferred way of defining class properties in Python and why? Is it Ok to use both in one class?

@property def total(self):     return self.field_1 + self.field_2 

or

total = property(lambda self: self.field_1 + self.field_2) 

Answer 1

For read-only properties I use the decorator, else I usually do something like this:

class Bla(object):     def sneaky():         def fget(self):             return self._sneaky         def fset(self, value):             self._sneaky = value         return locals()     sneaky = property(**sneaky()) 

update:

Recent versions of python enhanced the decorator approach:

class Bla(object):     @property     def elegant(self):         return self._elegant      @elegant.setter     def elegant(self, value):         self._elegant = value
