1__author__ = 'Kalyan'23notes = '''4 Decorators are higher order functions that add behavior to other functions. Python provides a simple syntax that makes5 it easy to use decorators on existing functions. This makes it easy to define higher order behaviors that can applied6 to other functions without repeating the same behavior in every function.78 To get an idea of how python folks introduces language features and spec them out read the PEP:9 http://legacy.python.org/dev/peps/pep-0318/1011 Review all the previous function lessons including nested functions if required and remember that12 functions are first class objects in python!13'''1415from placeholders import *1617# This is a function that adds enter log to another function by wrapping18# the func call with additional log behavior.19def log(func):20    # the inner function has access to outer func locals and they are bound at definition21    # time via a closure.22    def inner():23        print(("Entering func", func.__name__))24        return func()25    return inner  # returns a new func.2627# This is how you would do it, without any help from python.28def test_decorators_old_way():29    # A dummy method for testing.30    def get_hello():31        return "hello"3233    assert __ == get_hello.__name__34    assert __ == get_hello()3536    # Check that there is no log statement from the above invocation to get_hello in the pytest output and then37    # remove the assert.
