name decorator in python
# defining a decorator
def hello_decorator(func):
# inner1 is a Wrapper function in
# which the argument is called
# inner function can access the outer local
# functions like in this case "func"
def inner1():
print("Hello, this is before function execution")
# calling the actual function now
# inside the wrapper function.
func()
print("This is after function execution")
return inner1
# defining a function, to be called inside wrapper
def function_to_be_used():
print("This is inside the function !!")
# passing 'function_to_be_used' inside the
# decorator to control its behavior
function_to_be_used = hello_decorator(function_to_be_used)
# calling the function
function_to_be_used()
Output:
Hello, this is before function execution
This is inside the function !!
This is after function execution
