Creating a Chain of Function Decorators
Problem:Explain how to create and use a chain of function decorators in Python. Provide examples of defining and applying multiple decorators to a function.Solution:In Python, you can create a chain of function decorators by applying multiple decorators to a single function. Decorators are functions that modify the behavior of another function. To chain decorators, you simply apply them one after another in the order in which you want them to be executed.
Here's how to create and use a chain of function decorators:
def uppercase_decorator(func) :
def wrapper(*args, **kwargs) :
result = func(*args , **kwargs)
return result. upper()
return wrapper
def greeting_decorator(func) :
def wrapper(*args, **kwargs):
result = func (*args, **kwargs)
return f" Hello, {result} ! "
return wrapper
@uppercase_decorator
@greeting_decorator
def get_name() :
return " Alice"
result = get_name()
print(result) # " Hello, ALICE ! "
