In Python, please create the functions fancy_min(a, b) and minimum_of(numbers) without using the built-in min() function. Also, follow the notes for specific requirements.

1) fancy_min(a, b)

Input: two formal parameters: a and b

Output: return the minimum of a and b

Notes:

• a and b can either be a number or None

• if a is None, return b

• if b is None, return a

• if both are None, return None

• otherwise return the minimum of a and b

• do not use the built in function min()

2) minimum_of(numbers)

Input: numbers is a list of numbers (an item can be None as well)

Output: returns the minimum number in numbers.

Notes:

• minimum_of MUST use the function fancy_min

• you cannot use the Python min() function

• if numbers is empty, return None

• if numbers is None, return None
