Animal Quiz
Are you a fan of quizzes? Would you like to make one yourself? In this project, you’ll build an animal quiz. Even though the questions are about animals, this project can be easily modified to be about any other topic.
What happens
The program asks the player some questions about animals. They get three chances to answer each question—you don’t want to make the quiz too difficult! Each correct answer will score one point. At the end of the quiz, the program reveals the player’s final score
Putting it together
It’s now time to build your quiz! First you’ll create the questions and the mechanism for checking the answers. Then you’ll add the code that gives the player three attempts to answer each question.
1 Create a new file
Open IDLE. Under the File menu, select New File. Save the file as “animal_quiz.py”.
2 Create the score variable
Type in the code shown here to create a variable called score and set its starting value to 0.
3 Introduce the game
Next, create a message to introduce the game to the player. This will be the first thing that the player sees on the screen.
4 Run the code
Now try running the code. From the Run menu, choose Run Module. What happens next? You should see the welcome message in the shell window.
5 Ask a question (user input)
The next line of code asks a question and waits for the player’s response. The answer (the user input) is saved in the variable guess1. Run the code to make sure the question appears.
6 Build a check function
The next task is to check if the player’s guess is correct. Type this code at the top of your script, before score = 0. The code creates a function, called check_guess(), that will check if the player’s guess matches the correct answer. The two words in brackets are “parameters”—bits of information the function needs. When you call (run) a function, you assign (give) values to its parameters
7 Call the function
Now add a line at the end of the script to call (run) the check_guess() function. This code tells the function to use the player’s guess as the first parameter and the phrase “polar bear” as the second parameter.
8 Test the code
Try running the code again and type in the correct answer. The shell window should look like this.
9 Add some more questions
It takes more than one question to make a quiz! Add two more questions to the program, following the same steps as before. We’ll store the player’s answers in the variables guess2 and guess3.
10 Display the score
The next line of code will reveal the player’s score in a message when the quiz ends. Add it to the bottom of the file, under the last question.
11 Ignore case
What happens if the player types “Lion” instead of “lion”? Will they still get a point? No, the code will tell them it’s the wrong answer! To fix this, you need to make your code smarter. Python has a lower() function, which changes words into all lower-case characters. In your code, replace if guess == answer: with the line shown on the right in bold.
12 Test the code again
Run your code for a third time. Try typing the correct answers using a mixture of capitals and lower-case letters and see what happens.
13 Give the player more chances
The player currently has only one chance to get the answer right. You can make it a bit easier for them by giving them three chances to answer a question. Change the check_guess() function to look like this
How it works
To know if the player has gotten the right answer, you need to create a variable called still_guessing. You then set the variable to True to show that the right answer hasn’t been found. It’s set to False when the player gets the right answer.
