Question

Using Python, create a prefix Decorator function (or Closure) over the print function. The decorator (which takes two parameters) shall return a new function that accepts a single parameter string. When called and supplied with this string, the decorated print function shall first print its own, internal prefix followed by the supplied input.

For example:

first = Decorator("Joe:")

second = Decorator("Carl:")

first("Are you hungry")

second("yes")

Which would produce:

Joe: Are you hungry

Carl: yes

Answer 1

def Decorator(prefix):
    def fn(s):
        print(prefix, s)

    return fn


first = Decorator("Joe:")
second = Decorator("Carl:")
first("Are you hungry")
second("yes")
