Write and test the following function:

def max_diff(a): """ ------------------------------------------------------- Returns maximum absolute difference between adjacent values in a list. Use: md = max_diff(a) ------------------------------------------------------- Preconditions: a - a list of values (list of float) Postconditions: returns md - the largest absolute difference between adjacent values in a (float) ------------------------------------------------------- """ 

Add this function to the PyDev module asgn01.py. Test it from q7.py.

Examples:

>>> print(max_diff([0, 0, 0, 0])) 0 >>> print(max_diff([0, 1, 2, 3])) 1 >>> print(max_diff([5, 10, 20, 40])) 20 >>> print(max_diff([-5, 5, 7, 11])) 10 

Also side note, 1 function and 1 main module (your importing the function)
