Do you apply SOLID principles in your projects?

Yes, I actively apply SOLID principles in my Python projects to improve code quality and maintainability. For example:

• S (Single Responsibility Principle): each class or function is responsible for a single task.
• O (Open/Closed Principle): code is open for extension but closed for modification.
• L (Liskov Substitution Principle): subclasses can replace base classes without breaking the logic.
• I (Interface Segregation Principle): it's better to have several specialized interfaces than one general one.
• D (Dependency Inversion Principle): dependencies are built on abstractions, not on concrete implementations.

Here's an example of a simple class adhering to SRP:

class ReportGenerator:
    def __init__(self, data):
        self.data = data

    def generate(self):
        # Generate report
        pass

class ReportSaver:
    def save(self, report, path):
        with open(path, 'w') as f:
            f.write(report)

Here, report generation and saving are separated into different classes.
