To understand the meaning of classes we have to understand the built-in __init__ () function.

This is what you need if you want to compare whether or not two objects have the same contents, and you don’t care about where they’re stored in memory.The self-method works basically in the same way. To understand this better let’s take an example. myObject.myMethod(arg1, arg2), Python automatically transform it into myClass.myMethod(myObject, arg1, arg2). As you can see, the object itself becomes the method’s first argument. That’s what Python’s self is all about.1. Take this simple example: a = Test (); a.some_method_that_deletes_itself ();. Even if you for some reason ran del self in the method the object would still have a reference to it a. If you also had b = a somewhere then running del a would not delete the object as there is another reference to it now b.00:00 This video is about operations on bytes objects. bytes objects support the common sequence operations that you’ve used up to this point: The in and not in operators, concatenation and replication operators.. 00:18 You can do indexing and slicing.
