  "account": "Object-Oriented Programming (OOP) is a programming paradigm that structures code into objects, which are bundles of data (attributes) and behavior (methods). This approach enhances modularity, reusability, and maintainability of programs. In OOP, a class serves as a blueprint for creating objects, specifying the attributes and methods associated with each instance. For example, a Car class might include make, model, and methods such as start(), stop(), and acceleration(). An object is an instance of a class, representing an actual car built from the class blueprint.\n\nThe __init__ method, also known as the constructor, is automatically invoked when an object is created from a class. It initializes the object's attributes by setting their initial values. Often, the constructor accepts parameters that define the object's starting state, with the first parameter conventionally named self, referencing the specific object being instantiated.\n\nIn the example provided, a Car class is defined with attributes like make, color, max_speed, and model. Methods such as start(), stop(), and acceleration() are also defined within the class. By creating objects like car1 = Car(\"Toyota\", \"White\", 180, \"Hilux\") and car3 = Car(\"BMW\", \"Blue\", 260, \"X5\"), these objects are instantiated and can utilize the class's methods. For instance, calling car3.start() outputs \"The BMW car has started,\" while car3.stop(4) outputs \"The BMW car has stopped at 4pm.\" Additionally, car3.acceleration(260) demonstrates reaching a top speed of 260 km/h. Accessing object attributes, such as car1.color and car1.make, returns \"White\" and \"CrossOver SUV,\" respectively.\n\nThe four pillars of OOP—encapsulation, inheritance, polymorphism, and abstraction—form the foundation of this programming paradigm. Encapsulation, the first pillar, involves protecting data by keeping attributes private and exposing only necessary methods. This technique, illustrated in the MpesaAccount class example, involves using double underscores before attribute names (e.g., __balance) to make them private. Access to these attributes is restricted, allowing only authorized methods to modify or access them. This ensures data integrity and security within the object.",
