Python abstract classes 👻

Python abstract class example tutorial explained

#python #abstract #classes

#abstract class = a class which contains one or more abstract methods.
#abstract method = a method that has a declaration but does not have an implementation.

# prevents a user from creating an object of that class
# + compels a user to override abstract methods in a child class

from abc import ABC, abstractmethod

class Vehicle(ABC):

@abstractmethod
def go(self):
pass

@abstractmethod
def stop(self):
pass

class Car(Vehicle):

def go(self):
print("You drive the car")

def stop(self):
print("This car is stopped")

class Motorcycle(Vehicle):

def go(self):
print("You ride the motorcycle")

def stop(self):
print("This motorcycle is stopped")

#vehicle = Vehicle()
car = Car()
motorcycle = Motorcycle()

TLDR

# Prevents a user from creating an object of that class
# + compels a user to override abstract methods in a child class

# abstract class = a class which contains one or more abstract methods.
# abstract method = a method that has a declaration but does not have an implementation.

from abc import ABC, abstractmethod

class Vehicle(ABC):

@abstractmethod
def go(self):
pass

@abstractmethod
def stop(self):
pass

class Car(Vehicle):

def go(self):
print("You drive the car")

def stop(self):
print("This car is stopped")

class Motorcycle(Vehicle):

def go(self):
print("You ride the motorcycle")

def stop(self):
print("This motorcycle is stopped")


#vehicle = Vehicle()
car = Car()
motorcycle = Motorcycle()

#vehicle.go()
car.go()
motorcycle.go()

#vehicle.stop()
car.stop()
motorcycle.stop()

Your intentions are clear - Simply educate and not show off smartness by complicating the content, which other channels do. Keep up your work.

This was really helpful, thank you. Though I think at 4:57 the error arose from the vehicle = Vehicle() line, not from the motorcycle = Motorcycle() line, as your commentary implies at that moment.
