Python program to build flashcard using class in Python

In this article, we will see how to build a flashcard using class in python. A flashcard is a card having information on both sides, which can be used as an aid in memoization. Flashcards usually have a question on one side and an answer on the other. Particularly in this article, we are going to create flashcards that will be having a word and its meaning.

Let’s see some examples of flashcard:

Example 1:

Approach :

• Take the word and its meaning as input from the user.
• Create a class named flashcard, use the __init__() function to assign values for Word and Meaning.
• Now we use the __str__() function to return a string that contains the word and meaning.
• Store the returned strings in a list named flash.
• Use a while loop to print all the stored flashcards.

Below is the full implementation:

Python3

class flashcard:
    def __init__(self, word, meaning):
        self.word = word
        self.meaning = meaning
    def __str__(self):

        #we will return a string
        return self.word+' ( '+self.meaning+' )'

flash = []
print("welcome to flashcard application")

#the following loop will be repeated until
#user stops to add the flashcards
while(True):
    word = input("enter the name you want to add to flashcard : ")
    meaning = input("enter the meaning of the word : ")

    flash.append(flashcard(word, meaning))
    option = int(input("enter 0 , if you want to add another flashcard : "))

    if(option):
        break

# printing all the flashcards
print("\nYour flashcards")
for i in flash:
    print(">", i)

Output:

Example 2:

Approach :

• Create a class named flashcard.
• Initialize dictionary fruits using __init__() method.
• Now randomly choose a pair from fruits using choice() method and store the key in variable fruit and value in variable color.
• Now prompt the user to answer the color of the randomly chosen fruit.
• If correct print correct else print wrong.

Python3

import random

class flashcard:
    def __init__(self):

        self.fruits={'apple':'red',
                     'orange':'orange',
                     'watermelon':'green',
                     'banana':'yellow'}

    def quiz(self):
        while (True):

            fruit, color = random.choice(list(self.fruits.items()))

            print("What is the color of {}".format(fruit))
            user_answer = input()

            if(user_answer.lower() == color):
                print("Correct answer")
            else:
                print("Wrong answer")

            option = int(input("enter 0 , if you want to play again : "))
            if (option):
                break

print("welcome to fruit quiz ")
fc=flashcard()
fc.quiz()

Output:
