Python - Encapsulation and Data Protection

Which of the following is the correct syntax to define a setter for a property named value?

class MyClass:
    @property
    def value(self):
        return self._value

    # What goes here?

A@setter.value\ndef value(self, val):\n self._value = val

B@value.setter\ndef value(self, val):\n self._value = val

C@value.set\ndef set_value(self, val):\n self._value = val

D@value.setter\ndef set_value(self, val):\n self._value = val

Step-by-Step Solution

Solution:

Step 1: Identify correct setter syntax
The setter uses the property name with @value.setter and defines a method with the same name value.
Step 2: Check method name and decorator
@value.setter\ndef value(self, val):\n self._value = val correctly uses @value.setter and method value. Others use wrong decorator or method names.
Final Answer:
@value.setter\ndef value(self, val):\n self._value = val -> Option B
Quick Check:
Setter uses @propertyname.setter and same method name [OK]

Quick Trick: Setter decorator is @propertyname.setter with same method name [OK]
