PROJECT 8

Silly Sentences

In this project you’re going to put together a program that spits out a hilarious mixture of words — sort of like Mad Libs. To do this, you’re going to tackle string formatting for prettier printing.

This project’s object is to create templates for words that are randomly chosen from a list. The randomness of the words makes them absurd and, hopefully, funny enough to make you laugh out loud.

To complete this project, you

  5. Print the words into the template using formatting.

Insert Format Strings

Format strings let you fit changeable bits of a message into a template. That way it’s easier to present your messages, and it makes your code more readable.

>>> print("Hi there %s. You are such a good author."%"Brendan")

In IDLE, the strings are in green and ...
