Project: Mad-Libs Story Generator

Time to build your first project. A Mad-Libs game asks for a few words (a name, a place, an animal) and drops them into a story to create something funny. You will build one using variables and a small piece of new magic: the f-string.

What You'll Build

A short program that stores some words in variables and prints a complete story with those words slotted in. Change the words, run it again, and you get a brand new story.

The New Tool: f-Strings

An f-string is a string with an f in front. Anything inside curly braces is replaced with the value of that variable. It is the cleanest way to build text from variables:

Compare that to gluing pieces with + and str(). The f-string is shorter and much easier to read. You will use f-strings constantly from here on.

Step 1: Store the Words

Step 2: Build and Print the Story

Now slot the words into a sentence with an f-string:

Build It Yourself

Now put the whole thing together. Use the four variables and one f-string to produce the exact story below.

Make It Your Own

Change the words to whatever you like, and try adding another blank to the story (maybe an adjective or a second place). The playground below is yours to experiment in.

Challenge Ideas

• Add a food variable and mention it in the story
• Print a second line that reacts to the story, like a headline
• Make the number part of the sentence do math, for example {number * 2} legs

Key Takeaways

• f-strings slot variable values into text: f'Hi, {name}'
• Store each blank in its own clearly named variable
• Building small programs from a few variables is real programming
• Change the inputs, rerun, and watch the output change
