Discuss the concept of Python decorators and provide an example of how you would use decorators to measure the execution time of a function.

Question

Accepted Answer

Python decorators are functions that modify the behavior of other functions. They are commonly used for adding functionality to existing functions without modifying their code.

Decorators are defined using the @ symbol followed by the decorator function name.
They can be used to measure the execution time of a function by wrapping the function with a timer decorator.
Example: def timer(func): def wrapper(*args, **kwargs): start_time = time.time() result = func(*args, **kwargs) end_time = time.time() print(f'Execution time: {end_time - start_time} seconds') return result return wrapper @timer def my_function(): # Function code here
