I need python 3 help. from operator import add, mul def square(x): return x * x def negate(x): return -x def identity(x): return x

def triple(x): return 3 * x

def increment(x): return x+1

def increment_by(x, step): return x + step

 Returning Functions:

Q2.3: King of the argument.

We say that a function is a "king of the argument x" if after applying two functions to the same input, the output of one function is exactly twice as big as the output of the second one. For example, increment(1) is a "king of the argument" compared to square(1). Write a function, king_argument, which takes a one-argument function f and a value x.

It returns a function that takes another function g that returns a string specifying which function is a "king of the argument". Inspect the doctests for the exact messages.

Requirement: Include at least 3 assert statements that check the correctness of the input. Note, that one assert statement should check the correctness of the

input for the inner function as well.

def king_argument(f, x):

"""Returns a function that returns a string indicating what

function is a "king of the argument".

>>> num1 = king_argument(identity, 1)

>>> num1(increment)

'Second function is a king of the argument: 1'

>>> num1(triple)

'King cannot be determined'

>>> num2 = king_argument(increment, 1)

>>> num2(square)

'First function is a king of the argument: 1'
