LAB 3

Lab Description:

The Purpose of this lab was to create a menu that is linked to list of expressions that when selected executes the expressions chosen. Like Lab 2 this Lab starts off by assigning number of options to expressions to be executed.The difference is that these expressions,being locally in a while statement, are conditionally chained.

Code:

 

option = 1 
option = 2
option = 3
option = 4
option = 5
option = 6
option = 7
print ("1-The sum x + y")
print ("2-The difference x ┬ľ y")
print ("3-The product x * y")
print ("4-The quotient x/y")
print ("5-The remainder x%y")
print ("6-Whether x is less than, equal, or greater than y")
print ("7-Exit")
option = input ("Enter option # from menu to perform operation or Enter number (7) to Exit")
while option <7 :
          
           
        if option == 1:
                   X = input ("Enter X ")
                   Y = input ("Enter Y ")
                   Z = X + Y
                   print "X + Y = ", Z
                   print option 
                   (option == 2 );
                   option = input ("Enter option # from menu to perform operation or Enter nember (7) to Exit")
                  #Print option

        elif option == 2:
                   X = input ("Enter X ")
                   Y = input ("Enter Y ")
                   Z = X - Y
                   print "X - Y = ", Z
                   option = 3
                   print option 
                   (option == 3) ;
                   option = input ("Enter option # from menu to perform operation or Enter number(7) to Exit ")
                  #Print option

        elif (option == 3):

                   Z = X * Y

                   option = 4
                   print option

                   option = input ("Enter option # from menu to perform operation or Enter number (7) to Exit ")
