I am working on the file "08 Classes and OOP.ipynb".
The first task is:
A method is just a function that is part of a class. Since it is just a function, you can do anything with a method that you learned about with functions. You can accept positional arguments, keyword arguments, an arbitrary list of argument values, an arbitrary dictionary of arguments, or any combination of these. Your arguments can return a value or a set of values if you want, or they can just do some work without returning any values.
Each method has to accept one argument by default, the value self. This is a reference to the particular object that is calling the method. This self argument gives you access to the calling object's attributes. In this example, the self argument is used to access a Rocket object's y-value. That value is increased by 1, every time the method move_up() is called by a particular Rocket object. This is probably still somewhat confusing, but it should start to make sense as you work through your own examples.
If you take a second look at what happens when a method is called, things might make a little more sense:
Can you write Python code for it?

class Rocket():
    # Rocket simulates a rocket ship for a game,
    #  or a physics simulation.
    
    def __init__(self):
        # Each rocket has an (x,y) position.
        self.x = 0
        self.y = 0
        
    def move_up(self):
        # Increment the y-position of the rocket.
        self.y += 1

# Create a Rocket object, and have it start to move up.
my_rocket = Rocket()
print("Rocket altitude:", my_rocket.y)

my_rocket.move_up()
print("Rocket altitude:", my_rocket.y)

my_rocket.move_up()
print("Rocket altitude:", my_rocket.y)
