Lab Description:

This program is the same program I did in lab#2 but this time its incorporated in functions. It covers  functions, Boolean expressions and while loop. Basically everything I have learnt so far. It wasn’t difficult splitting my previous program into functions but i had a little problem figuring out how the menu should work.

Code:

def sum_numbers():
    x= int(input ("enter intger for x:"))
    y= int(input ("enter integer for y: "))
    print ("x+y= ",(x+y))
def subtract_numbers():
    x= int(input ("enter intger for x:"))
    y= int(input ("enter integer for y: "))
    print ("x-y= ",(x-y))
def multiply_numbers():
    x= int(input ("enter intger for x:"))
    y= int(input ("enter integer for y: "))
    print ("x*y= ",(x*y))
def divide_numbers():
    x= int(input ("enter intger for x:"))
    y= int(input ("enter integer for y: "))
    print ("x/y= ",(x/y))
def remainder():
    x= int(input ("enter intger for x:"))
    y= int(input ("enter integer for y: "))
    if x==0 or y==0:
        print ("Math Error. x or y can not be 0")
    else:
        print ("x%y= ",(x%y))
def compare():
    x= int(input ("enter intger for x:"))
    y= int(input ("enter integer for y: "))
    if xy:
        print ("x is greater than y")
    else:
        print ("x is equal to y")

print ("     WELCOME!")
print ("")
print ("Select an option")
print ("1- Sum of numbers")
print ("2- Subtraction of Numbers")
print ("3- Multiplication of Numbers")
print ("4- Division of numbers")
print ("5- Remainder of numbers")
print ("6- Compare Numbers")
print ("7- Exit")
print ("")
x= int(input("Choice: "))
if x==1:
    sum_numbers()
elif x==2:
    subtract_numbers()
elif x==3:
    multiply_numbers()
elif x==4:
    divide_numbers()
elif x==5:
    remainder()
elif x==6:
    compare()
if x==7:
    exit

while x!=7:
    print ("")
    print ("Select an option")
    print ("1- Sum of numbers")
    print ("2- Subtract Numbers")
    print ("3- Multiply Numbers")
    print ("4- Dvivde numbers")
    print ("5- Remainder of numbers")
    print ("6- Compare Numbers")
    print ("7- Exit")
    print ("")
    x= int(input("Choice: "))
    if x==1:
        sum_numbers()
    elif x==2:
        subtract_numbers()
    elif x==3:
        multiply_numbers()
    elif x==4:
        divide_numbers()
    elif x==5:
        remainder()
    elif x==6:
        compare()
    if x==7:
        break
