When to make a property

Question

I was just wondering, if I were to be using object oriented programming, when is the best time to make a property? What is it the most useful for?

Answer 1

You're talking about python? Properties are read-only, so you can use them to make sure that instance variables aren't changed without permission, especially in combination with a setter method

class Person():
def __init__(self, age):
self._age = age

@property
def age(self):
return self._age

p = Person(24)
print(p.age) # 24
p.age = 25 # error: can't set attribute

Answer 2

Talking about c#

Properties are used for data, you need outside the class.
Please stop using fields, use properties every time.

With a property you can check and validate the input with "set"
With "get" you can control the ouput.

A property enables you to do encapsulation. Protect the data inside the class.
