Is method is calling method or Is method is calling itself ? What does the statement in the description says ?

Question

The first argument in a method is always the object that is calling the method

Answer 1

example please. I dont really understand

Answer 2

I am taking about class.

"The first argument in a method is always the object that is calling the method."
What does this statement want to tell us ?

Answer 3

When writing a method for a class it is obligatory to make "self" the first argument of this method. "self" means that the method refers to the class and hence to the instantiated object.

Answer 4

a method call is of the form:

instance.method()

the 'method' function is bounded to a specific instance, wich is passed as first argument (usually called 'self') of the function...

so, a method should ever have at least one argument in its declatation (signature) to receive it, even if you do not pass it explicitly...

class Test:
def __init__(self,arg):
self.value = arg
def method(self):
print(self.value)

t1 = Test(42)
t2 = Test("forty-two")

t1.method() # 42
t2.method() # forty-two
