Building a Mad Libs Word Game in Python

#python #programming #beginners #tutorial

Mad Libs is a classic word game where one player prompts others for various words like nouns, verbs, adjectives, etc. without providing any context. The prompt words are then inserted into a story template full of blanks to create a hilarious or nonsensical story that the players read aloud for laughs.

Mad Libs has entertained generations of kids and adults since it was invented in the 1950s. Numerous television shows and games have also adapted the concept as an interactive storytelling format. Let’s learn how to code our text-based Mad Libs game in Python.

Learn about loops here: Python Loops: A Comprehensive Guide for Beginners

Step 1 – Setting up the game template

First, we must create our Mad Libs story template as a string in Python. This will contain the full story text with placeholders for where player input must be inserted, like {noun}, {verb}, etc.

For example:

story = “The other day my friend and I spotted a/an {adjective} looking {noun} on the sidewalk. My friend decided to {verb} it while I {verb}-ed.”

Step 2 - Prompt for words from a player

We will use Python’s input() function to prompt the player to enter words for each placeholder in the story template string. Let’s store each input in separate variables like:

adjective = input(“Enter an adjective: “)
noun = input(“Enter a noun:”) 
verb1 = input(“Enter a verb: “)
verb2 = input(“Enter another verb: “)

Step 3 – Insert words into the story template

Next, we insert the words stored in the variables into the story template using string concatenation to replace each {placeholder}.
For example:

story = “The other day my friend and I spotted a/an “ + adjective + “ looking “ + noun + “ on the sidewalk. My friend decided to “ + verb1 + “ it while I “ + verb2 + “-ed.”

Step 4 - Print out the full story

Finally, print out the full Mad Libs story to display to the player!

print(story)

At this point, we have built the basic functionality. Let’s look at some ways to expand the program next.

Adding Loops

Using loops, we can fill multiple blanks in the story without repeatedly prompting the player manually for each one.

For example:

    adjectives = []
    for i in range(3):
       adj = input("Enter an adjective: ")
       adjectives.append(adj)

    story = "...a/an " + adjectives[0] + "..." + adjectives[1] + "...extremely " + 
    adjectives[2] + ..."

Creating a GUI

Instead of a text interface, we can use the tkinter module to build a graphical user interface for a more interactive visual experience.

We first import tkinter to allow us to create GUI elements.

    import tkinter as tk

Create the main window

Using tkinter, we create a Tk() object, which will be the main window of our GUI.

    root = tk.Tk()
    root.title("Mad Libs")

Adding input fields

We use the Entry widget to create input fields to collect words from the user.

    noun_entry = tk.Entry(root) 
    noun_entry.pack()

# Repeat for other word types (verb, adjectives, etc)

Adding a text display box

We use a Text widget to display the final mad lib story to the user.

    story_text = tk.Text(root, height=8, width=40)
    story_text.pack()

Adding a Play Again button

We use a Button widget to create a clickable Play Again button to restart the game.

    play_button = tk.Button(root, text="Play Again", command=play_again) 
    play_button.pack()

    def play_again():
       # Reset game

...

Putting it together

We arrange all the GUI widgets using .grid() and .pack() for our layout.
We can now prompt the user for input, build the story, and display it in the GUI instead of just text printouts. The full code would connect the GUI elements to the game logic.

    import tkinter as tk

    # Main story template 
    story = "One day my friend and I found a {adjective} looking {noun} on the {noun}. My friend decided to {verb} it while I {verb}ed."  

    # Functions
    def play_again():
       # Clear entries
       adj_entry.delete(0, tk.END)
       noun_entry1.delete(0, tk.END)

       # Clear story  
       story_text.delete(1.0, tk.END)

    def generate_story():
       # Get values
       adjective = adj_entry.get()
       noun1 = noun_entry1.get()  
       noun2 = noun_entry2.get()
       verb1 = verb_entry1.get()
       verb2 = verb_entry2.get()

       # Create full story
       story_text.insert(tk.END, story.format(adjective=adjective, noun=noun1, noun2=noun2, verb=verb1, verb2=verb2))

    # GUI Setup
    root = tk.Tk() 
    root.title("Mad Libs")  

    # Input fields
    adj_entry = tk.Entry(root)
    adj_entry.pack()

    noun_entry1 = tk.Entry(root)  
    noun_entry1.pack()

    noun_entry2 = tk.Entry(root)
    noun_entry2.pack()

    verb_entry1 = tk.Entry(root)
    verb_entry1.pack()

    verb_entry2 = tk.Entry(root) 
    verb_entry2.pack()

    # Text display box 
    story_text = tk.Text(root, height=8, width=40)
    story_text.pack()

    # Play again button  
    play_button = tk.Button(root, text="Play Again", command=play_again)
    play_button.pack()

    # Run main loop
    root.mainloop()
