Inheritance established "is a" relationship between classes.

class Turtle;  
class TigerTurtle is a Turtle (but better);  
class BossTurtle is a Turtle (but better);

Underlying classes hold an inner object to the super class, everything from Turtle will be in TigerTurtle and BossTurtle.

In some languages that is configurable with public, private, protected keywords.

Relatedly, there's also composition, which establishes a "has a" relationship:

class TurtleTail;
class Turtle:
  var tail: TurtleTail; (has a tail);

Since Turtle is NOT a tail, but a whole animal, turtle should not inherit TurtleTail. But it HAS a tail, thus we add turtle tail as a property.

I'm only commenting because the actual python is practically pseudo code:


# A turtle class
class Turtle:
    shell=True

# A boss class
class Boss:
    authority=True

#A class that inherits from another
class TigerTurtle(Turtle):
    fuzzy=True

# Multiple inheritance, or "The Devil's Playground"
class TigerBossTurtle(TigerTurtle, Boss):
    #  shell, authority, and fuzzy are all true
    ...

It is simpler than my faulty memory remembers, time to learn python again 😁
