THIS Is How You Should Be Making Getters & Setters In Python

This is how you should be making getters & setters in Python. It's simple and doesn't require any change to existing variable names. In the example I changed "_name" to "fruit_name", but you don't have to do that, you can easily just call it "name".

This was the most easy tutorial for me to understand this super confusing thing. Thanks!

[ganzaian]

Big Man Ting, this is actually great stuff and simple

[LEGENDKINETIC]

Awesome dude. I finally understood it. 🎉

[lisav]

Thanks, you help me much for work and studies :)

[DerBarde]

Thanks, this will allow checking values before writing them

[Shao-LunHuang]

The only circumstance that I think can make the setter and getter useful is to add additional functionality like checking the validity of the input. Yet, I do not know whether this is a good practice :/

thank you so much i was so confused before i saw your video

there's as 400 long page articles and this pro achieved to explain it into seven minutes

What is the advantage of this property wrappers compared to use the class variable directly?
At the beginning you talk about private variables. But the variable "_name" is still not private with these property wrappers, right? Currently, it feels like #pragma in C to map one variable to another and I don't really see the advantage. It adds way more code compared to use the class variable directly. Am I missing something?

Very good, but, can you enlarge the screen?😊

[jasmeet]

Can't we just use "__get__" and "__set__" dunder method for implementing getters and setters in a class. Can someone explain ?

I thought declaring an attribute with an underscore makes it protected rather than private.

[dalkap]

Honestly that just seems longer and less readable to me, but if there's a good reason to use it I'm happy to be proven wrong!

[aventurileluipetre]

This is longer.... Why would I do that

[ordinaryBrain]

People he made this tutorial because it's a valid Python thing and its confusing. This is for those who wants to understand it. For example, I'm just following a curriculum that has this decorator in it. So this was useful to me. Stop hating.

namin' attribute startin' with 2 _ will make it private it is my observation

[Etk]

Seems like this method is old school and using it kind of downplays on the advantages of python. Regardless everyone says it's a good concept so I'll practice it I suppose?

Why not declare fruit name as private using the double underscore trick?

class Fruit:
def __init__(self, name):
self.__name = name

@property
def name(self):
return self.__name

@name.setter
def name(self, new_name):
if type(new_name) == str:
self.__name = new_name
else:
print("New name must be a string!")

fruit = Fruit("banana")

print(fruit.name)
fruit.name = 45 # here an error occurs
fruit.name = "orange"
print(fruit.name)

OUTPUT:
banana
New name must be a string!
orange

[techiehkr]

__name #private
_name #protect
name #public

This is really confusing i mean why we need a setter when we can access a private property outside a class I mean simply fruit.fruit_name = '''orange ' will change the name what is the point of setters and getters
