Write a Python program to create a simple math quiz.

 

Sample Solution:

Python Code:


import random

def display_intro():
    title = "** A Simple Math Quiz **"
    print("*" * len(title))
    print(title)
    print("*" * len(title))


def display_menu():
    menu_list = ["1. Addition", "2. Subtraction", "3. Multiplication", "4. Integer Division", "5. Exit"]
    print(menu_list[0])
    print(menu_list[1])
    print(menu_list[2])
    print(menu_list[3])
    print(menu_list[4])


def display_separator():
    print("-" * 24)


def get_user_input():
    user_input = int(input("Enter your choice: "))
    while user_input > 5 or user_input <= 0:
        print("Invalid menu option.")
        user_input = int(input("Please try again: "))
    else:
        return user_input


def get_user_solution(problem):
    print("Enter your answer")
    print(problem, end="")
    result = int(input(" = "))
    return result


def check_solution(user_solution, solution, count):
    if user_solution == solution:
        count = count + 1
        print("Correct.")
        return count
    else:
        print("Incorrect.")
        return count


def menu_option(index, count):
    number_one = random.randrange(1, 21)
    number_two = random.randrange(1, 21)
    if index is 1:
        problem = str(number_one) + " + " + str(number_two)
        solution = number_one + number_two
        user_solution = get_user_solution(problem)
        count = check_solution(user_solution, solution, count)
        return count
    elif index is 2:
        problem = str(number_one) + " - " + str(number_two)
        solution = number_one - number_two
        user_solution = get_user_solution(problem)
        count = check_solution(user_solution, solution, count)
        return count
    elif index is 3:
        problem = str(number_one) + " * " + str(number_two)
        solution = number_one * number_two
        user_solution = get_user_solution(problem)
        count = check_solution(user_solution, solution, count)
        return count
    else:
        problem = str(number_one) + " // " + str(number_two)
        solution = number_one // number_two
        user_solution = get_user_solution(problem)
        count = check_solution(user_solution, solution, count)
        return count


def display_result(total, correct):
    if total > 0:
        result = correct / total
        percentage = round((result * 100), 2)
    if total == 0:
        percentage = 0
    print("You answered", total, "questions with", correct, "correct.")
    print("Your score is ", percentage, "%. Thank you.", sep = "")


def main():
    display_intro()
    display_menu()
    display_separator()

    option = get_user_input()
    total = 0
    correct = 0
    while option != 5:
        total = total + 1
        correct = menu_option(option, correct)
        option = get_user_input()

    print("Exit the quiz.")
    display_separator()
    display_result(total, correct)

main()

Sample Output:

Two Machine Learning Fields

There are two sides to machine learning:

  • Practical Machine Learning:This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. It’s the mess of reality.
  • Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
