The first argument of every class method, including the __init__() method, is always a reference to the current instance of the class. By convention, this argument is named self. This argument fills the role of the reserved word this in C++ or Java, but self is not a reserved word in Python, merely a naming convention. Nonetheless, please don’t call it anything but self; this is a very strong convention.

In the __init__() method, self refers to the newly created object; in other class methods, it refers to the instance whose method was called. Although you need to specify self explicitly when defining the method, you do not specify it when calling the method; Python will add it for you automatically.

In all class methods, self refers to the instance whose method was called. But in the specific case of the __init__() method, the instance whose method was called is also the newly created object. Although you need to specify self explicitly when defining the method, you do not specify it when calling the method; Python will add it for you automatically.
