Python decorator for data analytics class

I need to create a decorator function that multiplies the input parameter of a function by ten before the function is called. Next, create a function called normal_function that takes an input value and displays the result. Test your decorator to ensure the displayed value is ten times larger than what was passed into normal_function.

def mult_decorator_function(a_normal_function):
  x = a_normal_function() * 10
  return x

@mult_decorator_function
def normal_function(x):
  print(x)

normal_function(10)
Solution

  • Have to have nested function for decorators, also need to have return instead of print:

    def mult_decorator_function(a_normal_function):
    def wrapper(x):
        x = a_normal_function(x) * 10
        return x
    return wrapper

@mult_decorator_function
def normal_function(x):
  return x

print(normal_function(10))

    Output:

    100
