Transcribed Image Text:1. Math Quiz:
Write a Python program(math_quiz.py) that displays simple arithmetic problems and asks users for the answer. The
program has two functions:
➤ Create the following constants:
RANDOM_MAX_NUM:
Initialize with 20 (upper range for randomly selecting two numbers for math
RANDOM_MAX_OP: Initialize with 4 (upper range for randomly selecting a number between 1 and 4)
main()
problem)
Initializes counters for score (number correct) and number of tries
> Calls fMathQuiz()
>
Uses Boolean value returned by fMathQuiz() to see if user was right or wrong
> Updates user's score and number of attempts appropriately
Asks user if they want to play again (y or n)
Validate user's response. Ask again if what user entered is not y or n
>If user entered y, loop back for another math problem
>If user entered n, "Your score: N correct in M attempts." and quit the program
fMathQuiz()
➤ Chooses two different random integers between 1 and RANDOM_MAX_NUM (inclusive)
➤ Randomly picks one of the following four arithmetic operators: +, -, *, // (use RANDOM_MAX_OP)
> Computes correct answer for chosen numbers and operator, but does not display it
➤ Displays the arithmetic problem using the two numbers and the operator
Examples:
19 // 3 =
5-3=
14 * 2 =
> Waits for the user to enter an answer
>If user's answer is correct, print "Correct!" and return True
>If user's answer is wrong, print "Wrong! Correct answer is:" with the correct answer, and return False
