List, Dictionaries and Iteration

QuizDb = []

# Dhruva's Info
QuizDb.append({
    "Firstname": "Nikhil",
    "Lastname": "Chakravarthula",
    "Age": "15",
    "Height": "74 inches"
})

# Tejas Info
QuizDb.append({
    "Firstname": "Tejas",
    "Lastname": "Chakravarthula",
    "Age": "11",
    "Weight": "130 pounds"
})

In this I created a function which asks questions like a test using dictionaries. This will take each dictionary and convert it into a list of questions.

# This cell defines a function that I will use to execute the quiz

def ask_questions(QDb):
    correct_cnt = 0
    total_cnt = 0
    for dict_item in QDb:
        person_name = dict_item['Firstname']
        for key in dict_item:
            if key == 'Firstname':
                continue
            else:
                question = "what is " + person_name + "'s " + key
                correct_answer = dict_item[key]
                user_answer = input(question)
                if user_answer == "exit":
                    break
                total_cnt += 1
                if correct_answer == user_answer:
                    correct_cnt += 1
                    print("Your answer is correct")

                else:
                    print("Your answer is incorrect")

        if user_answer == "exit":
            print("Bye!")
            break
    print('you answered: ', correct_cnt, '/', total_cnt, "Correct")

ask_questions(QuizDb)
# This cell has a while loop

def list_num_inclusive(x,y):

    x = int(x)
    y = int(y)

    if x >= y:
        print("ERROR!!! Starting value must be less than ending value. Please try again.")
    else:
        print("Here are your numbers!!!")
    while x <= y:
        print(x)
        x += 1

starting_value = input("What is the starting value? (Inclusive")
ending_value = input("What is the ending value? (Inclusive")

list_num_inclusive(starting_value, ending_value)

Your answer is correct
Your answer is correct
Your answer is incorrect
Your answer is correct
Your answer is correct
Your answer is incorrect
you answered:  4 / 6 Correct
Here are your numbers!!!

This function below uses a recursive loop and this loop can repeat itself untill a specific condition is met and in this case takes the dictionary value and increments itself while adding to a sum. It is exactly like a factorial

def example_recursive(x):
    x = int(x)
    if x < 10:
        x += 1
        x=example_recursive(x)
    else:
        print("End of recursive loop")
    return x

def example_recursive_dict(dict_obj, NN):
    #dict_obj['val'] = int(dict_obj['val'])
    print('inside example_recursive_dict, val is: ',dict_obj['val'])
    if dict_obj['val'] < NN:
        dict_obj['val'] += 1
        dict_obj['sum'] += dict_obj['val'] 
        #print('inside if')
        example_recursive_dict(dict_obj, NN)
    else:
        print("End of recursive loop")


#recursive_var = input("What number should we start with?")
#recursive_var=example_recursive(recursive_var)
#print(recursive_var)


def example_by_reference(dict_obj):
    dict_obj['val'] += 1

dict_test = {'val': 2, 'sum': 0}
print(dict_test['val'])
example_by_reference(dict_test)
print(dict_test['val'])
example_by_reference(dict_test)
print(dict_test['val'])
dict_test['val'] = 0
dict_test['sum'] = 0
example_recursive_dict(dict_test, 5)
print('summation is done, value is: ', dict_test['sum'])

inside example_recursive_dict, val is:  0

End of recursive loop
summation is done, value is:  15
