# (Python Example for Beginners)

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))

menu_list = ["1. Addition", "2. Subtraction", "3. Multiplication", "4. Integer Division", "5. Exit"]

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

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

def get_user_solution(problem):
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

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_separator()

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

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

main()
``````

Sample Output:

```************************
** A Simple Math Quiz **
************************
2. Subtraction
3. Multiplication
4. Integer Division
5. Exit
------------------------
16 + 16 = 32
Correct.
Exit the quiz.
------------------------
You answered 1 questions with 1 correct.
Your score is 100.0%. Thank you.```

## 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. Itâ€™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.
