Title

Decorators and their uses in python

Describe your Talk

Decorators in Python are functions that allow you to modify or extend the behavior of other functions or methods without altering their code. A decorator works by wrapping the original function in a "wrapper" function, which can execute additional code before and/or after calling the original function.

We also discuss some non-obvious uses of decorators. For example, decorators can implement memoization, caching the results of function calls or even make a function self-destruct after one use. Additionally, decorators can simulate retry logic by automatically retrying a function if it fails, which is especially useful for network requests.
