Question

Assignment Content PROGRAM DESCRIPTION Make a program that will allow the user to select a choice from the following options: A-getCount B-getSum C-checkNum D-getFactorial X - Exit Each options (A,B,C) must have its own user-defined function. The program must repeat the program until the user enters "X". Options are: 1. getCount. The module is designed to encode numbers until user enters "x" and determine the number of positive and negative numbers of the encoded numbers within the module. 2. getSum. The module is designed to encode numbers until user enters "X" and will compute and print the sum of the encoded numbers within the module. 3. checkNum. The module is designed to encode a number and determine if the encoded number is prime or not prime. 4. Factorial. The module is designed encode a number and determine the factorial of the number using a built-in math function.

Answer 1

#PYTHON PROGRAM FOR THE ABOVE GIVEN PROBLEM

#imported math for built-in factorial method requirement

import math

#getCount method printing the count of negative and positive numbers

def getCount():

    countNeg = 0

    countPos = 0

    number = input()

    number = number.lower()

    while number!='x':

        number = int(number)

        if number<0:

            countNeg+=1

        elif number>=0:

            countPos+=1

        number = input()

        number = number.lower()

           

    print("total positive numbers:",countPos)

    print("total negative numbers:",countNeg)

#getSum method to print the sum of the numbers entered

def getSum():

    ans = 0

    inp = input()

    inp = inp.lower()

    while inp != 'x':

        inp = int(inp)

        ans+=inp

        inp = input()

        inp = inp.lower()

    print("sum is:",ans)

#isPrime method to check whether a number is prime or not

def isPrime(n):

    if n==1:

        return False

    if n%2==0:

        return False

    a = int(n**(1/2))+1

    for i in range(3,a,2):

        if n%i==0:

            return False

    return True

def checkNum():

    num = int(input())

    print("is the number prime?:",isPrime(num))

    

#method to get the factorial of the number entered using built-in factorial method

def getFactorial():

    num = int(input())

    print("factorial is:",math.factorial(num))

#main method that contains the driver code

def main():

    while True: #the loop continues until the user presses 'x'

        print("A. GetCount")

        print("B. GetSum")

        print("C. CheckNum")

        print("D. GetFactorial")

        print("X. Exit")

        choice = input()

        choice = choice.lower()

        if choice=='a':

            getCount()

        elif choice=='b':

            getSum()

        elif choice=='c':

            checkNum()

        elif choice=='d':

            getFactorial()

        elif choice=='x':

            break

        else:

            print("You made a wrong choice.")
