Show me the steps to solve Write a Python program that consists of the following:

a$.$ a function that returns a temperature between $30$oC and $42$oC$.$

b$.$ a function that, given two temperatures, returns the difference between them. c$.$ a main$()$ function that tests the two functions.

$2.$ Extend the first function so that:

a$.$ the maximum and minimum temperatures are given as parameters.

b$.$ a third parameter is specified which indicates the maximum temperature change between $2$ consecutive temperatures
