How to fix NotImplementedError: abstract methods must be implemented in Python

Hello, Dedicated Coders! 🖥️💡

We're excited to share with you our newest video, "How to solve NotImplementedError: abstract methods must be implemented in Python". 🎥 This series is meticulously designed to arm you with knowledge 🧠 and skills 🛠️ to overcome frequent coding challenges.

Today, we will decipher 🔎 and resolve a common error faced by Python coders: the bit hard to solve NotImplementedError: abstract methods must be implemented. Here is a snapshot of the code of the video:

Troubling Scenario: ❗️
from abc import ABC, abstractmethod

class AbstractClassExample(ABC):
@abstractmethod
def do_something(self):
pass

class AnotherSubclass(AbstractClassExample):
pass

x = AnotherSubclass()

Unwanted Result: 🚫
TypeError: Can't instantiate abstract class AnotherSubclass with abstract methods do_something

Effective Resolution: ✔️
from abc import ABC, abstractmethod

class AbstractClassExample(ABC):
@abstractmethod
def do_something(self):
pass

class AnotherSubclass(AbstractClassExample):
def do_something(self):
print('Doing something')

x = AnotherSubclass()

Desired Output: 🏁
Doing something

In this detailed walkthrough, we will illuminate 💡 the underlying cause of this error, and offer a comprehensive explanation: The error is caused by not implementing an abstract method in a subclass. The fix implements the abstract method in the subclass. 🎯
