Can you explain what design patterns are in programming?

Design patterns are proven solutions to common tasks and problems that frequently arise in software development. They are descriptions or templates that can be reused to simplify architecture and improve code quality.

Main advantages of patterns:

• Improve code readability and maintainability
• Facilitate communication among developers, as patterns have widely accepted names
• Help avoid common mistakes

Example: The "Singleton" pattern guarantees that a class has only one instance and provides a global access point to it.

In Python, design patterns are applicable just like in other languages, although the syntax and language features may influence their implementation.
