I am learning both Greek and Python right now, so I decided to make a simple program that quizzes you on the translations by providing it in Greek and asking for English, and if you provide the English, it will output the Greek if it is in the dictionary.

Feel free to take and modify this for your own uses if interested! It would be as simple as replacing the Greek dictionary and references with anything else. :)

import random, sys

greekTranslation = {
    'Γεια σας': 'Hello',
    'Καλημέρα': 'Good morning',
    'Καλησπέρα': 'Good evening',
    'Ευχαριστώ': 'Thank you',
    'Παρακαλώ': 'Please',}

def practiceGreek():
    greekPhrase = random.choice(list(greekTranslation.keys()))
    print('')
    print(f'What is the translation of "{greekPhrase}"?')
    print('')
    answer = input('Your answer: ')
    if answer.strip().lower() == greekTranslation[greekPhrase].lower():
        print('')
        print('That is correct!')
        print('')
    else:
        print('')
        print(f'Incorrect! The correct translation is "{greekTranslation[greekPhrase]}".')
        print('')

def translateToGreek():
    print('')
    print('What would you like to translate into Greek?')
    print('')
    englishPhrase = input().strip().lower()
    reverseTranslation = {v.lower(): k for k, v in greekTranslation.items()}
    greekPhrase = reverseTranslation.get(englishPhrase)
    
    if greekPhrase:
        print('')
        print(f'The Greek phrase is: "{greekPhrase}"')
