What components and elements should be included in a framework?

A framework in Python typically includes the following key components:

• Core — basic classes and functions providing the main logic and architecture.
• Modules/Packages — sets of functional blocks, e.g., for database access, web servers, templates.
• Configuration — mechanisms for setting framework and application behavior.
• Error handling and logging — tools for catching exceptions and recording logs.
• Tests — built-in or recommended test scenarios to verify functionality.
• Documentation and examples — for quick start and understanding usage.

Elements often included in frameworks:

• Routing (for web frameworks) — defining routes and handlers.
• ORM (Object-Relational Mapping) — for database interaction.
• Middleware — intermediate request handlers.
• Tools for database migrations.

Example of a simple routing component:

class Router:
    def __init__(self):
        self.routes = {}

    def add_route(self, path, handler):
        self.routes[path] = handler

    def handle_request(self, path):
        if path in self.routes:
            return self.routes[path]()
        return '404 Not Found'
