I was studying for an exam and wanted to make a tool that functioned a little bit differently than quizlet.
This code will read in questions and multiple choice options then quiz you on them in a random order.
It will also go over the questions that you missed.
I made it last week and it is surprisingly helpful. I plan to add fill in the blank options and some more customization in the future.
Tell me what you think:

You would read in a file like this:

.
What shape is a tire?
Square
Triangle
Circle~
Rectangle
.
What grows on trees?
Money
Cows
Apples~
Strawberries
.
What is not a normal household pet?
Fish
Dog
Cat
Giraffe~
.
What flies in the air?
Dove~
Penguin
Tree
Dog
.
What color is snow?
Black
White~
Blue
Red
.
What color is a firetruck?
Red~
Black
Green
Yellow

The '.' marks a new question
The '~' marks the correct answer

It is not much but I figured it may help someone out.

[Goodies]

1) You should not be using some strange proprietary format. You should use CSV's.

Code

What color is a firetruck?,Red~,Black,Green,Yellow

etc...
2) You should not be trying to re-invent the wheel.
3) You should be using pandas to actually read/sort these types of applications.

PHP Code


<?php 
import numpy as np
import pandas as pd

try:
    input = raw_input
except NameError:
    pass

quiz = pd.read_csv("test.txt")
quiz = quiz.reindex(np.random.permutation(quiz.index))  # randomize the dataframe
quiz.reset_index(drop=True, inplace=True)  # reset the indexes so they don't fuck me up.
correctAnswers = 0
totalQuestions = 0

for i in range(len(quiz.Question)):
    question = quiz.Question[i]
    answers = [quiz.Answer1[i], quiz.Answer2[i], quiz.Answer3[i], quiz.Answer4[i]]
    correctAnswer = ""
    for j, answer in enumerate(answers):
        if answer[-1] == "~":
            answers[j] = answers[j][:-1]
            correctAnswer = answers[j]
    if correctAnswer:
        answers = dict(zip(list(np.random.permutation(["a", "b", "c", "d"])), answers))  # randomize answers, too
        print("{}) {}\nA) {a}\nB) {b}\nC) {c}\nD) {d}".format(i+1, question, **answers))
        choice = input("> ")
        if answers[choice.lower()] == correctAnswer:
            correctAnswers += 1
        totalQuestions += 1

print("Your Score: {}/{}".format(correctAnswers, totalQuestions)) 


Your file should look like (note: the first line header is VERY important):

Code

Question,Answer1,Answer2,Answer3,Answer4
What color is a firetruck?,Red~,Black,Green,Yellow
What color is snow?,Black,White~,Blue,Red
What flies in the air?,Dove~,Penguin,Tree,Dog

It's all good. String manipulation is a very useful thing to know, but you should also utilize readily available and well-tested/well-supported frameworks (like pandas and numpy) when possible instead of re-inventing the wheel. I'm not going to lie, I do the same thing fairly often.

[bet4r00t]

I have a lot to learn xD
I like looking around in someone's code :p

I'll try this out :D

I re-wrote it to support fill in the blank questions as well.
I also have a 'question formatter' program that will format questions to be read by the quizzer.

Goodies will be happy to know that I used some of his advice.
I wanted to stay away from using a non-default library though

[labroca]

This is actually better than quizlet, I did not believe it would be at first.

[TheWarOwl]

it's basic, but very cool ^^ thank you for posting. I'll be sure to use this.

[DipDuo™]

This is actually better than quizlet, I did not believe it would be at first.

Glad you like it. I honestly use it all the time to study for tests. it really comes in handy when I am trying to study from old multiple choice quizzes.
