Method encapsulation in English is known as "method encapsulation" or "function encapsulation." It refers to the practice of bundling related data and functions that operate on that data within a single unit, such as a class or a module. This approach helps to organize code, improve maintainability, and promote reusability.

There are several benefits to method encapsulation:

  1. Abstraction: By bundling data and functions together, the complexity of the code is reduced, making it easier for developers to understand and work with.

  2. Modularity: Method encapsulation promotes modularity, which is the practice of breaking down a large system into smaller, more manageable pieces. Each module can be developed, tested, and maintained independently.

  3. Reusability: Encapsulated methods can be easily reused in other parts of the application or in different projects, reducing code duplication and development time.

  4. Maintainability: When methods are well-encapsulated, it becomes easier to maintain and update the code. Changes can be made in one place without affecting other parts of the code.

  5. Flexibility: Encapsulation allows for flexibility in modifying or extending the functionality of the code without affecting other parts of the system.

Here's an example of method encapsulation in Python:

```python class BankAccount: def init(self, initial_balance): self._balance = initial_balance

def deposit(self, amount):
    self._balance += amount

def withdraw(self, amount):
    if amount <= self._balance:
        self._balance -= amount
    else:
        print("Insufficient funds")

def get_balance(self):
    return self._balance

Usage

account = BankAccount(1000) account.deposit(500) account.withdraw(200) print(account.get_balance()) # Output: 1300 ```

In this example, the _balance attribute and the related methods (deposit, withdraw, and get_balance) are encapsulated within the BankAccount class. This organization makes the code more modular, maintainable, and easier to understand.
