In python, please include docstring as well for every function

It is a well-known phenomenon that most people are easily able to read a text whose words have only two characters flipped, provided the first and last letter of each word are Not changed. For example, I dn'ot gvie a dman for a man taht can olny sepll a wrod one way. (Mrak Taiwn) Write a function scramble(word) that constructs a scrambled version of a given word, randomly flipping two characters other than the first and last one. Then write a program that reads a sentence/phrase and prints the scrambled words. Use these sentences for your test cases: 1. You can't have the cake and eat it too. 2. A gentle answer turns away wrath, but a harsh word stirs up anger. 3. The love of god does not find, but creates, that which is pleasing to it. The love of man comes into being through that which is pleasing to it. (Martin Luther)
