Hello everyone ,
Please what is the difference between when we name an attribute by self.message and when we name it as message like an argument of a method like here :
def talk(self,message)
    print({} sad : {}".format(,message))

def talk(self,message)
    print({} sad : {}".format(,self.message))

and thank you .

What I have tried:

In case 2 the parameter "message" passed to the talk function is ignored.

If your code was complete - which it isn't, it's missing a close bracket, then ...

"self.something" refers to a field, method or property of the current class instance called "something", in the same way that "my car glove box" would reference to the specific glove box on your car, and have no interest in the content of the glove box on that car over there, you know - the grey one.

So if you put your mobile in the glovebox of your car and then come out in my car with me, you don't expect to find you mobile in my car's glove box - my car is a difference instance of the class of "cars" from your car.

In Python, self refers to the specific instance you are working with at the moment, and self.gloveBox refers to the current car's glove box.

When you provide a parameter of the same name though, you access that without self because you are talking about the specific value that the method was called with rather than a property of any specific class instance.
