Python Decorators Explained: Log Execution Time Like a Pro
Ever wondered how to measure how long a function takes to run without cluttering your code? In this video, we build a Timing Decorator. This is a powerful, reusable piece of code that logs exactly when a function starts, when it ends, and the total execution time.
What we will build:
Understanding "Higher-Order Functions."
Writing the @timer decorator.
Handling arguments and return values with *args and **kwargs.
Applying the decorator to real-world data processing tasks.
