What are some advanced Python techniques I should know?

Some advanced Python techniques include decorators, context managers, and generators. Would you like to explore one in detail?

Yes, tell me more about decorators.

Decorators are a way to modify or enhance functions or methods without changing their code. They are often used for logging, access control, and caching.

Can you give me an example of a decorator?

Sure! Here's a simple example of a decorator that logs the execution time of a function:

import time

def timer(func):
    def wrapper(*args, **kwargs):
        start_time = time.time()
        result = func(*args, **kwargs)
        end_time = time.time()
        print(f"{func.__name__} executed in {end_time - start_time} seconds")
        return result
    return wrapper

@timer
def my_function():
    time.sleep(1)
    print("Function executed")

That's really interesting! How do context managers work?

Context managers allow you to allocate and release resources precisely when you want to. The most common way to use them is with the with statement, which ensures that resources are properly managed.
