asyncio is a Python library for writing concurrent code using the async/await syntax.
asyncio allows for non-blocking I/O operations
It provides a way to write asynchronous code in a synchronous style
asyncio is built on top of the event loop, which schedules and executes coroutines
Examples of asyncio-based libraries include aiohttp and aioredis
Multithreading is the ability of a program to perform multiple tasks concurrently.
Multithreading allows a program to utilize multiple CPUs or cores.
It can improve performance and responsiveness of a program.
Threads share the same memory space and can communicate with each other.
Examples include web servers handling multiple requests simultaneously and video games rendering graphics while processing user input.
Pub sub is short for publish-subscribe. It is a messaging pattern where senders of messages, called publishers, do not program the messages to be sent directly to specific receivers, called subscribers.
Publishers send messages to a topic or channel without knowing who the subscribers are.
Subscribers receive messages from the topic or channel they have subscribed to.
Pub sub is commonly used in distributed systems a...
Decorators are functions that modify the behavior of other functions or classes without changing their source code.
Decorators are used to add functionality to existing code without modifying it.
They are defined using the @ symbol followed by the decorator function name.
Decorators can be used to add logging, caching, authentication, and other features to functions and classes.
Examples of decorators in Python includ...
Asynchronous programming is a programming paradigm that allows multiple tasks to run concurrently without blocking the main thread.
Asynchronous programming is achieved through the use of callbacks, promises, and async/await functions.
It is commonly used in web development for handling user input and making API calls.
Asynchronous programming can improve the performance and responsiveness of an application.
Examples ...
Design patterns are reusable solutions to commonly occurring problems in software design.
Design patterns provide a standard terminology and a common platform for communication among developers.
They help in making code more flexible, reusable, and maintainable.
Examples of design patterns include Singleton, Factory, Observer, and Decorator patterns.
